actually yes, forget the scores for casual Wii games, score system does not work for some Wii games
Yeah, IMO, people put too much weight and faith in outright number scores. Number scores have a purpose and a use, but the more important part of a review is the write up. I've had much more fun with Mario Party 5 (my favorite MP) than GTA4. Not that I'd argue MP5 is better than GTA4, but I certainly have had more fun with that 70% game than the 97% one.
A lot of the casual games are really hit and miss on a personal level. I love the Mario Party series, but rented Mario & Sonic once, and hated it. The only thing I really remember is almost having an anyeruism attempting to do the 100M dash.
