I'd also like to remind you all that by definition, the average score for the contest should be exactly 5. The contests aren't getting worse; there are more voters and they are becoming better critics.
For everyone's reference, Egg Palace has inflated scores because at the time it was one of the largest and most detailed SRB2 stages made. Obviously nowadays we know better, but most people gave it rather significantly high numbers because of that, myself included. In hindsight it's certainly not a 10, but at the time the concept of a single player stage you couldn't beat in a minute or two was a big deal.
