Been playing a lot of this game recently. I really enjoy the military sandbox thing, as I just really like experimenting with different vehicles and weapons systems and tactics. Being sort of a newbie in these kinds of hardcore games, this game was the first one I could *really* pick up and play. I'll continue exploring the scenario generator whenever I want to muck around with some obscure military equipment. I just wish there was *more* of it. I know it's a bit spoiled to ask for Wargame Red Dragon's arsenal size, but I did bounce off that game for not adhering to general common sense in tactics and being too competitive and clicky. And the main draw there was all the cool stuff you got to use from the toy box.
Over all, I know I'll continue enjoying AB as I get better at tactics, and it'll remain my "short play session" wargame for the near future. But I think I'll finally start getting my rounds on Combat Mission soon enough. That, or Flashpoint Campaigns.
Addendum: I also just remembered the AB devs are working on the sequel, which I would love to play soon.
