To hack.

Well much of my opinion on hotels has already been stated in earlier posts. The only hotel that I ever liked was Fooville. Unlike hotels, tests are a bit different story as they always have some form of gameplay present (eg. reach the goal). Eyecandy and level design do play some role in quality. TSF seems to have a lot of unskilled level makers, which is apparent from the quality of levels hosted. Skilled level makers will often create fine tests and such can be really fun and addictive. Personally I've always liked EvilMike's tests.
