Unfortunately, Mass Effect 2 on the XBOX 360 has the same stability issues which plagued Mass Effect 1---namely, after a seemingly-random period of playing, it pops up the message "This disk is unreadable ...". This is rather annoying, as when I play games I like to set aside a day and blast through them straight-through-like, and this issue is like a time-limit on playtime.

I suppose a limit on playtime is not such a bad thing for my health and sanity, but if it was to be introduced, I'd prefer some sort of configurable timer/clock reading (one of my favourite features of Master of Orion 3 was its clock which popped up at a specified time telling you to go to bed). I doubt that ME2's issue was, however, intentional on the part of the developers. Perhaps the QA team never played that long? Though that's hard to believe; I would imagine they played 8+ hours on some days.

Next step: install game to console. Just learned from here that this is possible, hopefully it will fix my issues, as they manifest as 'disk read' so, if there's no disk to read...
