Is it better to play Oblivion without the mods first?

Depends. Normally I'd recommend playing vanilla first. I mean, you may be totally happy with it as is. I preferred the modded version, but if I hadn't played through on vanilla first, I'd have nothing to compare the modded version to!![]()
It's the only decent RPG around, so you are wrong.
Most are fail because they are 3rd person. 1st person is much more immersive
For some reason after enabling it all I just couldn't really get to grips with it, getting knocked over in fights all the time etc.The dialogue is a bit shaky but the scale of the game is still impressive. I played around 70hrs then realised I hadn't got the mod (Pahncrd's) installed properly, lolFor some reason after enabling it all I just couldn't really get to grips with it, getting knocked over in fights all the time etc.
