Why so Starship Troopers hatred? :) Both of the ST games were cool:
Starship Troopers: Terran Ascendancy is quite cool squad based rts strategy and I play it for a loooong time because of all that cool things in this - like power armors inspired by a book or ability to shoot nukes at bugs :D Also it has some cool maps for its time (some of theme really beautiful).
Starship Troopers FPS is also cool. Its easy arcade shooter with movie sequences. It has almost no story line but it has cool arcade missions like go there, kill some bugs, go elsewhere, kill some more etc. I am not saying it was great game but it wasn't bad. Of course if you want some Half-Life like game you should look elsewhere. But if you are looking for some cool shooting ST was a good game for you :)
