I disagree. Oblivion had terrible mechics, and the fact that levelling took forever
If you want to know what long leveling is like, play Morrowind. I play for an hour or two (at level 1), and level up once, if I fight a lot and use trainers.
I don't really care the bad graphics but I played the game for a while and got pretty bored fast. I know that the game is older and stuff, but Skyrim, to me, is a hundred times better than Oblivion.
Oblivion is as good, if not better, than Skyrim. There is more role-playing, better quests, and cooler factions to join, and a longer and more interesting main questline. I have trouble finding issues with that game.
