In case anyone is considering this and wants an additional level of simplicity added to LWJGL, Slick is a great library for easy 2D graphics. http://slick.cokeandcode.com/

Yes it is a great engine.

I am using Clojure & Slick2d for the Action RPG I am developing so I can say Clojure is a great choice for games!

I even open sourced my game: (with video) https://code.google.com/p/clojure-rpg/

You can play it here (older version , not so fun but works!) http://resatori.com/cyber-dungeon-quest-alpha-1
