You know, one of the original devs is still working on Battlezone, he released a big patch last year which makes the game run on modern PCs with support for xbox 360 controllers etc. The entire game is freeware now.

MDK2 (Dreamcast) (Total sleeper hit of epic proportions, adored the game, still own it)
Red Faction (PS2) (The original's release I believe wasn't preceded by much hype)
I liked BattleZone but I liked this game even better.
It was called Uprising: Join or Die

I enjoyed playing Capitalism back in the days on the PC, along with Einhander for the Playstation.
