OK, so I guess the next question is what is a normal sized battle for AS? In BattleTech we normally have a company of mechs with air (always) and armor and/or infantry (sometimes) support on each side so this is what we are used to. In the past when we have played AS we used companies (some times with mostly with out armor/infantry but never anything else) for each player and maybe it was the old rules, maybe we were doing it wrong, and/or maybe we were doing some (many) thing wrong, but it just did not feel like battletech to us.
There is no formal "standard" sized game, but I find that 400-500 points per side makes for a company sized battle that can be set up, played out, and packed up in about 2 hours. Judging by chatter in this and the After Action Reports forum, that seems like a pretty common game size.
What "feels like Battletech" is something that's going to be defined 6 different ways by 5 different BattleTech fans. If what you like about CBT is something that's related to what's lost in the change in granularity in Alpha Strike, then sadly Alpha Strike will never give you that thing you liked. For example: if you feel like the notion of a mech operating at 100% capacity up until its removal from the game goes against BattleTech, then AS will never address that for you. Because largely, yes. Mechs (normally) suffer no problems at all until all armor is shot off and by the time it's taking critical hits, it's gonna be dead more times than not anyway by the end of that same round. This is exacerbated when you sensibly combine fire on targets.
However you can change your perspective. As I mentioned upthread, the "lowest level of playing piece" shouldn't be considered the single mech, but the single lance of 4 of them. If you feel that a mech suffering no ill effects from fire at all until all armor is gone doesn't feel like battletech, consider that's pretty much how it works in CBT on a different level of scale... a single hit location doesn't (usually) suffer any ill effects from hostile fire until each and every last pip of armor is shot off. Same game rules phenomenon... but in CBT you don't consider your mech's arm to be a distinct playing piece from the mech's other arm and in AS you shouldn't consider 1/4th of a lance to be its own individual battle element either.
Anyway, here's some of the things I think AS does that makes it a great "feel" for BattleTech:
Lights are useful (albiet arguably *too* useful... but I'll take that over "why ever field light mechs?" that permeates regular/CBT)
It's a game about unit tactics rather than a gladitorial game between warbot pilots
It seamlessly integrates combined arms. Yeah, Mechs are the stars of BattleTech, even still in Alpha Strike. But would you want to play Chess without pawns? I want my "pawns" in my BattleTech, and Alpha Strike integrates them better than CBT does.
It allows engagements up to the sizes that are commonly discussed in fiction and sourcebook lore. If you're used to playing company sized battles in CBT, then playing Battalion sized battles under AS should be easy as punch.
It streamlines and standardizes tech. I don't care about the difference between a Medium Laser, an ER Medium Laser, a Clan ER Medium Laser, and etc. Alpha Strike doesn't either (beyond the stats conversion process, that is). But that's a personal preference thing. I find it an improvement to the game that noone has to worry about the slight range advantage of this weapon versus that. If that kind of thing is what you like, then CBT may be your better fit. But I think the standardized ranges is good because it streamlines the game. Medium range is 24" no matter what. Long range is 42" no matter what. Making ranges a universal standard allows for tactics to be about other things (like flanking, screening, feinting, thrusting, etc). Again, talking preferences, but I think AS feels more like a wargame set in the BTU and CBT is more like the mech gladiatorial combat scale game. (and for that, why not just use ATOW or Solaris VII rules? But I digress)
If you bring in the SPAs and lance formation bonuses, the pilots ironically become more important than in the lower-granularity scale CBT. (although CO is now bringing SPAs and Lance bonuses to CBT, I believe).
Can you explain more about what you felt was not "BattleTechy" about Alpha Strike? Could be just different opinions, but also could have been expectations that were faulty. Could also even have been something being done wrong or something that errata has since fixed.
