If it were done in today's environment, I think they would have to compete with shows like Star Wars Rebels and the like. Plus I think that if they made the Battletech Cartoon in this day and age it would be all CGI, so the battles would definitely be more intense. But on the other hand, because the Btech franchise isn't as BIG as Star Wars in terms of popularity, they would need some way to advertise it in a way that would get more people to watch it. After all, the big reason why shows like Rebels and Clone Wars were so successful was because they had a bigger fanbase in terms of popularity of source material. If Battletech got another show, I think they would have to make it for a more...mature audience since the original cartoon was more or less meant for kids of that kind of mind set at the time.
After all, it was the cartoon that got me into Battletech in the first place, not the tabletop game, not the MechWarrior games, not even the books. It was the cartoon and the toys that came with it that got me into it. At the time, I had no idea that it was just the tip of a much bigger iceberg than what I already knew. Which is why I think that Battletech deserves another shot at either the small screen or the big screen. But if done RIGHT, as in getting a better budget, better story, better writers, better director, I think a Battletech movie or TV show would be a big hit. Given the technology we have today, I'd say the time is right for a new Battletech show or movie.
But again, the problem is advertising. What we need to do is advertise a Battletech movie or show in a way that will get people interested and WANT to see it. We can't say stuff like, "It's like Game of Thrones, in space" or "Star Wars has NOTHING on this!" It has to be unique in a way that will get people to want to watch it.
