When I play games these days I often see things happening that I feel are scripted, but somehow it doesn't hinder the games pleasure a lot. I like to see how those scripted sequences are used, I like to see things I technically understand being used well. Sure, you know how things are triggered, you can imagine the entities behind them but when I play, that's not what I think of. I'm curious to see how this stuff is being used and enjoy it as well.
Of course, games have lost their magic somewhat after you played a lot of them and especially when you know how things are made, for me they're no longer so 'special' but at the other hand, things become more interesting because I understand more and more gameplay mechanics and games stimulate my creativity.
For example, I played Codename Panzers: Phase one recently. I liked it, it has great detailed environments and the units look and feel real, but the gameplay didn't live up to it at times. Something I hate is endless streams of enemies coming at you, and especially with such graphics I expected the gameplay to be more realistic as well. This makes me thing about how different parts of a game interact with each other and how they work together. You can't simply mix up stuff like where the graphics are cartoony but the story is dead-serious.
Mapping isn't my only interest, I model and do textures as well and I'm working out concepts and I'm on a programmers education. So there's lots of things I can explore and look into and maybe that's what makes games so much more interesting to me even though I can spot flaws and all much faster. About flaws, I believe it's not little flaws that count, taking into consideration that developers have limited time to do their job. The larger, more structural things like gameplay aspects or whole map parts count much more. I don't care for some misaligned textures in a backalley. I care much more if that backalley is long, boring and repetetive and needs to be travelled through 5 times before I can make progress. Design > technical.
