I don't plan to buy "a lot" of games, have to finish all those I bought already, some bought years ago (and probably won't ever finish the ones on PC).
Totalling those I'm sure to buy, I can't reach 20, even if I'm not sure they all will be released in 2007:
1. Fire Emblem (Wii)
2. Dragon Quest: Swords (Wii)
3. Final Fantasy Cristal Chronicles (Wii)
4. Final Fantasy Tactics Advance 2 (DS)
Then, those I'll probably buy when I finish every other games I got:
5. Shirokishi monogatari (PS3)
6. Opoona (Wii)
7. Soul Calibur Legends (Wii)
8. Heavenly Swords (PS3)
9. Metroid Prime 3 (Wii)
10. Guilty Gear XX: Accent Core (Wii)
Then, probabably, inbetween, if I get the PS3 this year :
11. Rogue Galaxy (PS2, if it ever comes out in Europe)
12. FF XII (PS2)
13. God of War II (PS2)
14. No More Heroes (Wii)
