To be honest, they are only really good to me, if i never had them, but always wanted them eg: OOT.
Personally i'd like to see some games like on 360's arcade, where games are developed for the wii, instead of ported.
i wish when they'd put the games on the VC they'd put the NTSC versions up cause in europe we get the inferior PAL versions. I think the NTSC games run at 60 Htz and PAL at less, im not sure though, anyone know in detail the differences between NTSC and PAL VC games?
There are a lot of good Virtual Console games out there.
But as GoldenAssassin said, go to vc-reviews.com and check out games that look interesting to you, watch the video on it, etc. before you buy it 'cause there's no way to get your points back if you bought a game you don't like.
