Yes. In my view, that's a nostalgic gaming session, rather than having any point in relation to completion. I did Master Runs in TimeSplitters: Future Perfect years ago, but I'll still pop it in to enjoy playing it. Since this is more of an open interpretation without concrete guidelines per game, I'm using it as a personal record of what I feel is unfinished, beaten, completed, etc.

And if I don't have any personal motivation to do anything beyond what I've already done, then that's completion to me. Bear in mind, I'm not just going to start beating games and calling them completed because I'm done with them.

For example, Dead Space 2(which I'm going through now) won't be marked as completed, although I'm likely going to wind up with 57 out of the 58 achievements in it. I'm making a judgement call to just finish Zealot rather than going through the Hardcore mode. I have 400 unfinished games; I have to make a judgement call as to whether I'd like to go through another game, or spend at LEAST 6 hours that are needed to make a Hardcore run . Even though I'm going to be done with the game, and will probably never play it again, I'm not going to mark it completed because I haven't done everything in it.

Even if the game is awesome and down the road you feel like playing the game once more?

For anyone wondering, for me, Completion means that I'm likely never going to return to play the game again.
