I found a coupon online to let me order the Xbox 360 at $250--this was my "sweet spot" price point. It arrives in a week or so and I am pleased that so many 360 games are so inexpensive--often for only $20-30(!)
Thinking to the last year, only a few games captured my attention long enough to finish. I finished a lot of games like 70+% but never bothered to finish completely. The ones I did finish were:
(1) Metroid Prime 3
(2) Resident Evil 4 Wii
(3) Advance Wars DS 2
(4) Final Fantasy XII DS
That's it...though MP3 and RE4 were both spectacularly good in my opinion. I need more games like them...
