it's an awful question..:)
For my point of view, Sins belongs to my top 5 of recent games (it's a hard choice due to high competition).
1. Neverwinter nights 2 (expansion pack included)
2. Mass Effect
3. Crysis (full very high setup in 1920*1200)
4. Sins of a Solar Empire+entrenchment
5. Call of duty 4 (mode hardcore in multiplayer)
After that my classics games favorites :
1. Dune 2
1 bis : Wing commander 3&4 (5 was good but not as good as the 3 and 4), and Privateer 1&2 'the darkening)
3. Baldur's gate, Icewind dale series
4. Dragon quest 8
5. Resident Evil Series (especially Code veronica and the 4th)
6. XWing and Tie Fighter
7. Age of wonders
8. Civilization 1 (the best one..:))
9. The Settlers (the 1 from far, even if the last one is near to first)
10. Tekken and Soul Calibur series (all of them..:))
