I own a Wii but this is the first time I have purchased a non Nintendo console as well. I really enjoyed games like Excite Truck, Trauma Center, Zelda, and Metroid. After playing these games I had high hopes for it. I couldn't wait for boxing, golf, RPGs... games I wouldn't normally be interested in, however, all great things come to an end and I'm finding myself playing the Wii less and less.
Granted, games like Mario Galaxy, Resident Evil: Umbrella Chronicles and Metal of Honor: Heroes 2 are awesome but I think the quality of other titles has plummeted overall. This is not the case with Nintendo made games as they are clearly getting better but third party games are generally getting worse in graphics and in controls... SSX Blur, Godfather, Need for Speed, Elebits and Red Steal blow away most of what's out there right now and those are launch titles.
I'm not Wii bashing because I hate it, I just wish companies would put adequate effort into their Wii projects (note the keyword here is adequate).
Is anyone else playing Wii less and less? Is anyone considering selling their system? I'm not at the stage of selling mine but most of my friends already have. It's really sad because although my friends are more into Playstation they bought a Wii first for the same reasons I did (sports, something different) but even though we have different tastes, we all agree that the reason for loosing interest in the Wii is its lack of quality third party offerings.
