1. Mass Effect (360)- It came out on the 360 months before there was a pc version and I prefer consoles to the pc
2. Mass Effect 2 (360)- I had already completed the 360 version of ME 1 so I could transfer my data into ME 2 on the 360
3. Final Fantasy 13 (PS3)- It was the best version and it's as simple as that 720p with 1080p video vs 576p with 720p video
4. Eternal Sonata (360)- It was on the 360 first and I don't sit and wait to see if a game I want is going to land on a preferred system like many people seem to do.
5. Tales of Vesperia (360)- It was on the 360 first and apparently it's the technically better version since it runs in 720p while the PS3 version is 640p
6. Street Fighter 4 (PS3)- Technically the 360 version is better since it's a higher resolution but the dpad on the PS3 is so much better for fighters
7. Resident Evil 5 (360)- The 360 version had better anti aliasing over the PS3 version but the deal breaker is when the demo was released on xbl before psn so I had got use to controlling the game with a 360 controller
8. Dragon Age Origins (PC)- As I said before I am primarily a console gamer but reviewers and anyone who had seen and played both versons recommended the pc version highly over the console versions. There is a fine line between preferring something and being loyal to the point of bordering on stupid.
My room mate recently got the PS3 version of the game since he doesn't have a pc that can run the game and the gameplay and graphics does seem to be miles ahead on the pc version.
9. Ninja Gaiden 2 (360)- see number 4 for explanation. Also NG2 on the 360 has more gore and is more challenging than the PS3 version.
10. The Last Remnant (360)- I did not have a pc that could run the game fluently at the time but apparently my 360 can't run the game fluently either.
Edit I forgot some)
11. Borderlands (PC)- It was very cheap on steam during the summer sale
12. Need for Speed Undercover (PC)- It was very cheap
13. Prince of Persia (PC)- cheap
