When 4E came out, it was good. It was all about the race, class and powers you chose, rather than the magic items you had (magic items are way less powerful in 4E, good for DM's, bad for players). It was insanely easy to DM, but very hard to kill PC's due to healing surges (PC healing ability). It was fun to play. However, with the errata that never seemed to end and the changes they made the game should now be 4.5E or 5E! As an example, all attacks were meant to be rolled for, no auto hits yes Magic Missile I'm talking about you. Now they've gone back to how it used to be, an auto hit spell that now has crap damage.
Going over to RPGNET now to pu my 2 bobs worth in!
