[General Discussion] One game at a time or multiple games at once?

I recently bought a couple of games in one go.
When I make multiple game purchases within a short period of time or simultaneously, I usually play one at a time. Not strictly "finish one before you go on to another" but more like "play a good chunk of one before trying out the other". However, it might as well be one at a time strictly, because whenever I buy multiple games it's almost always because they were both cheap games. There's usually a reason that the games are cheap and they're usually not the most spectacular. Regardless I play through at least an hour of the games even if I end up never touching them again other than to go straight back to EB at a loss incurred from trading.

Right now, I have resolved to not trade any of these (if ever) until at the very least, beating them:
Okami, Valkyrie Profile 2, Final Fantasy XII, Disgaea 2, Valkyrie Profile: Lenneth, Final Fantasy VI Advance.

While that's a small backlog, I still make myself myself play on at a time even now, because I have a really bad habit of rechecking everyone's equipment, skillset, and status whenever I go back to a game I haven't played for a long time, which can take up to 30 minutes.

Jam it back in, in the dark.
