I own 21 DS games. I'll be over at Best Buy tomorrow to pick up Clubhouse Games, which will be my 22nd game.
It's very rare for me to own so many games so early on in a console's life-cycle. The DS's promise for a new way to play games keeps keeps me buying new games - I just can't wait to see what each developer has done with the unique control scheme. The amazing thing about my 'collection' is that no 2 games are alike. It seems that each game is of a completely different genre, control scheme, or gameplay mechanic. Of course, since it's on the DS, it's also unlike any other game across my entire gaming collection. For me, that speaks loads about the DS as a gaming platform.
