Prepare for a more convoluted, flawed levelling system that encourages gaming the system. And NPC graphics that didnt age well at ALL. And Combat that didnt age particularly well either. However Cyrodiil is very pretty, a pleasure to explore (if pretty cookie-cutter C&P after a while), the story is pretty cool, magic system is way WAY better than Skyrims, as are the faction questlines. Especially the Mages Guild. Oh and The Shivering Isles is probably still the most memorable piece of DLC I ever played. It managed to make an already great base game look bland in comparison. It has its ups and down. If you can get past its flaws and warts, its really really fun.
