I want to talk about tiles. Tiles are a nice texture to use because they have a lot of innate detail. They have grout, which provides opportunities for nice normal maps and variations in phong/envmap specularity, they can have cracks on them which looks cool, and the tiles themselves can have cool designs or just alternating colours. The problem with tiles though is that this inherent detail is misinterpreted for ease of use. As nice as it is to slap a tile texture down and give yourself a pat on the back as you sip you freshly prepared congratulatory cognac on the rocks, it's not at all that simple - as usual, como siempre.
Tiles are actually a pain in the ass to lay down in real life. I tiled my toilet and bathroom once. It was horrible. You have to cut here, lay there, measure this, and it's all such work. This experience led me to look at game tiles in a different light. No longer can I drop a tile texture down, rotate it 45 degrees and think no one will look twice.
