When you have a big quantity of games, it takes some time to choose which game to play. With about 7-8 systems being played consistent, I have a hard time figuring which games to play. Maybe Super Mario Bros 3 on the Nes? Or Bioshock 2 on the 360? Or a handheld game, like River City Ransom EX on the GBA?

I might start playing a game I really want but after 10 minutes, I remember I had some other game to play and I end up switching games.

How do people here choose which games to play at every moment? Do you give each game a number and use a randomizer program? Choose a group of maybe 15 games and start eliminating one after one and finally getting 3-4 games only? Or just choose one at random and start playing?
