Already playing BF3 more than cRPG, will likely spend a lot of time on Skyrim and Dark Souls too.
Among TES, I only seriously played Oblivion, and I liked it. The reason is mainly because I'm part of the group of gamers that do like mods. A lot of mods. Since Morrowind, TES are extremely modular (everything is moddable) and have an incredibly productive modding community (super big mods for morrowind and oblivion are still in active dev today). I totally agree Vanilla Oblivion is kinda meh. Poor, easy, exploitable... But with mods you can get the game you want. There are thousands of custom creatures/areas/equipment/magic, but also AI mods, difficulty mods, leveling mods, quest mods... Virtually all the issues of the vanilla version are settled, and features are added. In the end, you can get a deeper, harder and more interesting experience than any of the earlier games. If you don't want to install mods, don't complain about the game, it's your own fault
