I just finished the Dawnguard DLC for Skyrim over vacation and now I'm going back and playing Oblivion again, picking up my last save before closing the last Oblivion gate. Playing Skyrim sort of "trained" me further on how to get the most out of an open-world RPG, and now I'm exploring a bunch of facets of Oblivion I totally missed before.
My reigning fav OWRPG is Skyrim, but I'm also enjoying or have enjoyed:
Kingdoms Of Amalur: Reckoning
Two Worlds 2
Anyone else like these kinds of games and have some favorite to share?
