Oh man I haven't played any new games for about 2 years, so my list'd be older games, but who cares eh?
It's hard to list 'em but here goes:
1. Heroes of Might and Magic IV
2. Civilisation 2 (only cos I haven't played the newer ones probably
)
3. Baldur's Gate II
4. Warcraft 3
5. Elite 3: First Encounters
6. Red Alert 2 (only cos I haven't played the newer ones prob. )
7. Transport Tycoon
8. Age of Mythology
9. Syndicate Wars
10. Unreal Tournament
damn I could hardly think of 10 games I used to like playing!
