Yes, those items are overpriced now because people didn't had the chance to even list new prices because of the fees, frankly I would be happy If I manage to take out 1/3 of the current valuation. It's an interesting time to play with those things for sure, when Enj scales holy cow the moon.
Games on Enjing that have some potential are Six Dragons and finally something is happening with Space Misfits. Spase Misfits probably had the slowest development time but it could be quite big once it launches properly as an MMO.
Wax is a strange one, I'm only "playing" Alien Worlds and Rplanet, those are not games though, passive click once per day staking apps. Dark Country looks interesting though.
