I can understand the strategic elements being fun.
I hate tower defense games
I mean there's strategy involved, but
barelyhonestly, nobody's made a game (like a video game, not forum or board games) that is strategic the way I want
at least, not that I've ever played. I'm very interested in playing MAG just to see if it's what I'm looking for
crysis 2 (I've never played the first :c) is maybe the closest I've found to what I want
if not that, then timeshift
