I did managed to reduce my compulsive buying spree, not by THAT much (i reached the 1000 mark), but at least now i'm more organized, and decide to make an extra buy only if i can afford it (i mostly always can, i'm really well organized for this stuff, but that's not the point).
Criteria for Null: an endless/without goals game, games part of a series that follows a chronological order (for example, i'm not playing Yakuza 3 before i beat Yakuza 2), parts of an episodic game (same rule as before), games with technical issues (like corrupted save file, or not working at all), or games that i don't intend to play.
About collections: if it's a small number of games (example: Power Stone Collection) i list the games in it individually, in case of big ass gynormous collection of old and/or arcade games, i just list the collection as one game, for convenience and since many old games, especially arcade ones, usually don't have much in a way of replay value or goals.
From now on i'm categorizing/listing every game downloaded via Playstation Network under the "PSN" category, despite of the Playstation console it works on (which is/are listed in the game info sections).
BTW, i use the Stealth Save feature a lot, don't care about statistics, i just wanna keep my memory card "clean".
