The simplest way to describe Space Aggressor is to call it “Dungeon Keeper meets a shmup.” In the game you take the role of the evil space empire, defending yourself against the lone pilot. It’s a really neat concept, actually.
However, the game itself is frustrating as hell. This is partly due to the clunky interface that requires more micromanaging than is fun or necessary, and partly due to the fact that your opponent happens to regenerate like Wolverine in a full body cast! Seriously, what’s the point in attacking his primary weapon (or shields, or engine) when he can replenish it to 100% before I can even queue up another round of fighters?
Sadly, the creator has taken an unfortunate stance toward user feedback. If the interface sucks, it’s “because it’s a strategy game.” If the game is frustrating, then you’re just not understanding the subtleties behind the game mechanics. With that kind of attitude, I imagine Space Aggressor will forever remain a mediocre game with an interesting concept behind it.
