If you're looking for easy (most of the time :p) games to perfect, here are the ones I did ...

The way Steam counts these "perfect games" is a pita. Some have the "profile features limited" tag, others are removed from store, some are both, and Steam does not take them into account (or most of them, because it turns out some games removed from the store are still counted ...). Anyway, here's what I make up of all that.
