Say that a multi-plat game comes out across several plaftorms. You go with the PlayStation version, does it bother you to then pick up the sequel or further installments for Xbox, or Nintendo, instead of the console you've started buying the series for? I'm sort of struggling with this, on occasion. Sometimes it's just easier to find stuff across platforms instead of all on one. But at the same time, you can't keep the games together because the unwritten rule is you must organize your games by console. It's a really petty thing, it annoys me a lot.
What do you say? Pick up whatever version is most convenient, or try to get the whole series all on the same platform?
