It seems like you can't think of any aspect of Deus Ex that hasn't been improved upon recently. Instead, you just say "the whole package." To me that suggests that you just really like Deus Ex, and don't like other games because they aren't exactly the same as the ones you like: DE and SS2. Impossible to make a definitive list. Diablo 1&2, Fallout 1&2, Baldur's Gate 1&2, Counter-Strike, and Dawn of War come to mind though. The only things ME has in common with Gears of War are the cover system and UT3 engine. ME2 has less RPG elements than ME1, but the character classes, experience/skill system, upgradeable items, and NPC party mechanics are all there. If anything ME2 is more RPG-ish than Deus Ex, which was very much RPG-lite.
