If the disk space is actually used for something useful, I have no problem with it. Something like The Witcher being 14 gigs for the current Enhanced Edition/Director's Cut doesn't bother me, because it's a huge game. That's also unusually large, and most stuff I've gotten recently has been less than the size of a dual-layer DVD, and most of that no bigger than a single-layer DVD. A lot of it's only been a couple hundred MB up to 1-2 GB for indie stuff or non-AAA games that are just as fun.
The one game that really irritated me with unnecessary largeness was The Force Unleashed, which was a completely ridiculous ~30 GB for a rather short game that doesn't seem to have a particularly large number of unusually high-res textures or anything. If it weren't such a half-assed port, I'm sure they could easily have fit it in, say, 8 GB. That's one of the few things I did get rid of right after I finished it, because that's just a stupid amount of disk space to waste on something I'm not going to play regularly, unlike a lot of smaller things I leave installed on the off chance I feel like playing them for some reason.
