I actually really like the Starship Troopers game. I felt it was a refreshing break from the d20 norm.
Starship Troopers includes enough fluff to let a non-loremaster into the game just by a glance through the rulebook (or reading select parts to him), while also letting you go through a fair amount of situations.
All in all, the thing about Starship Troopers is that you can play almost any game, but you will almost always play the same character. It's pretty much mandatory to start as the same class (depending on how much the person running the game sticks to the rules), but the uniformity feels almost refreshing. You're a soldier of the future. Not an uncultured barbarian, not a squishy mage. You're a soldier, and you're putting those playthings behind you, and killing some bugs.
