There are lots of small games in the gnome-games package and there are simply too many. It looks kind of bloated with that many games installed by default. So I suggest that you just have 2 or 3 games instead of the whole package.
What I'd like to see is an option to select which games you want. Now all games are being installed and you can also remove all of them, but you can't install or remove some of the games.
I don't like card games, but I like to play Gnometris. An option to select the games you'd like to install would be nice. Also an option to a install or remove each game seperately after installation.
