SunAge

Incredibly buggy, packed with design flaws, seemingly a decade old... SunAge is a real-time strategy disaster.

With SunAge, it's really a question of whether you're willing to put up with clumsy UI and control scheme to play a game that, for the most part, feels like it was or could have been made 10 years ago, and even then it would have been a middling game. You're far better off reinstalling something like StarCraft or Command & Conquer: Red Alert. Evoking nostalgia is certainly a worthy goal for a game, but there's got to be something compelling worth staying for after the memories fade.
