Back then, and to some extent even today I don't really consider ammo in the same location as the gun "logical". The thought process I had back in the day was that sticking ammo in an arm was asking for an early ammo explosion that'd take out your entire 'Mech, because arms are the most easily breached part of a 'Mech. The deeper you could bury it in the torso and its thick armor, the better, particularly for bins with fewer shots. I get the feeling the original designers thought the same way. Yes, I do question why sometimes the gun is in the right torso and the ammo in the left, but often funny little fluff pieces followed that.
But if you are willing to go with the thought process of "sticking ammo in the arm was asking for an early ammo explosion that'd take out the entire mech because arms are most easily breached location", why is it that far of a leap to "sticking ammo in the otherwise empty torso is asking for an early ammo explosion that'd take out the entire mech, as torso locations are hit more often than arms are. And then the ammo is by itself and blows up."
Indications are that the original designers thought that they should protect ammo with things like heat sinks. And so they did that. And then when the rules to the game changed (i.e. heat sinks disappeared into the engine), they decided that they didn't want to change all the mech descriptions (i.e. the Marauder had its ammo in the LT which at some point had heat sinks in it; after the extra heat sinks vanished, they apparently didn't want to go and rewrite the mech description to have the ammo in the RT instead). The issue here is primarily a practical one, not one of design intention.
I'm not sure about the specifics of those things, but the rules changed a lot from Battledroids to the following edition. The way they are now is the way they've been for over two decades, and are very unlikely to change.
The first two pages of this discussion generally revolved around what these mechs were like in the earliest editions of the game. And from records folks could find, the Marauder originally had heat sinks in with its ammo. And the one example of a Crusader record sheet being filled out as an example in the first edition of the game showed the Crusader with heat sinks in with it's torso ammo as well.
I realize that things, at this point, are unlikely to change. Especially given that apparently when this was discussed with the game designers on this forum, their response was "It'd take too much work to go and fix all the mechs that need fixing at this point. We have more important stuff to do." Which indicates that they realize that it could use some fixing. But that also it would be opening a huge can of worms that probably is best left alone.
With the modern design rules full of double-heat sinks and crit-for-weight saving items, unit that have only a single slot of anything are rare as hell. I don't know that has anything to do with a deliberate design choice so much as it does with the fact that 'Mechs are being designed with every slot being considered now. That said, authors might just be more sophisticated now.
Sure, but again, even the mechs that are retroactively applied to the earliest time frames that are put together in later editions of the game (Merlin, Lineholder, whatever) are designed to avoid obviously blowing up when they could have been designed to obviously blow up.
Well, there's your problem right there. Catalyst's authors and developers, which is to say the people who also design the majority of the canon 'Mechs, are trying to create a cohesive game world that doesn't conform exactly to the game's abstract rules. In the interest of advancing this integrated view of the storyline and universe, there are a lot of concepts relating to 'Mechs, their uses, and their development that have no bearing on the table-top. Ignoring the canon storyline means ignoring the entire basis around which canon 'Mechs are designed. If you don't care about the "fluff', you don't need to use canon 'Mechs at all!
Here's the thing at this point in the discussion. From my point of view, no, this isn't a *huge* problem. Mostly, I was interested in the early half of this discussion, where folks dug through all their old edition, archived game materials, and discovered things like that the Marauder used to have heat sinks in with its ammo, and that in the first (or second) edition rulebook that didn't come with pre-made record sheets, the Crusader example listed it as having 5 heat sinks in each torso location along with its ammo. As I was curious as to whether this was all an intentional arbitrary decision to do these things, or if it was just the result of the evolution of the game. And all indications are that, in fact, it is just a result of the evolution of the game. And, say, that the poor Marauder having that LT suicide bomb is just an artifact of the Marauder being one of the first mechs designed in the history of the game, the game evolving around it, and the game designers being more concerned with consistency with mech listings, "game history", and the pure practical reality that going and changing everything would be a pain and not the result of some game designer saying "Yes, I realize that putting this ammo here is an obviously stupid idea, but I'm going to do it anyway as I like seeing things blow up!"
At this point in the discussion, however, what I'm most baffled by is that folks are bending over backwards to *defend* this sort of thing. Which I'm completely confused by. Like, yes, it isn't *that* big of a deal. You can avoid it by just not using these legacy mechs. Or, ya know, just thinking it is funny when you are forced to use one for whatever reason and it blows up (as noted, in my recent games with a Marauder vs an Archer, my Marauder blew up twice from an unfortunate ammo shot. Which was just funny and entertaining, as I was using the Marauder to test out the theories discussed in the "Archer vs Marauder: Fight!" thread, and the end result was "Well, the Marauder is likely to do worse than hoped. As it's ammo blows up a lot." But if I'm playing a game to be competitive, I'm going to leave the Marauder in the box...). But the response to this issue that I understand is:
"Yeah, it is, in fact, silly that those mechs have that ammo placed like that. But, ya know, you do what you can and either don't use them, work around it, or don't worry about it and hope they don't have blasters."
The response I don't understand is:
"It isn't a silly bug! It is a feature! The game *wants* those mechs to blow up! And you should want them to!"
But I guess people do things that I don't understand all the time.
