1. Are the games fun (Is it a nice experience? Was the gameplay enjoyable?) ->*Most companies don't care about this anymore :/ *
2. Is the price reasonable
3. Is there a lot of variety in the games (*Ahem* PS3 & Xbox = practically all FPS, cept a few)
4. Last factor, though not that important, is graphics. Gotta look decent, but DOESN'T need to be amazing. Spend more time on gameplay
