Ya I really like them too. Was mainly MW for a very long time. Didn't play Skyrim until about a year after the GotY edition came out. In the last year though I've played more Oblivion than the other two. I never played vanilla, struggling through Oblivion with a FCOM install for the longest time and didn't enjoy it much at all. On a whim I trashed that install and started building one with a more considered approach. Much more enjoyable. I've got 4 main characters at the mo, each with about 80 hours on the clock. One's a thief/archer for random adventuring. Another has done the MQ and started Knights of the Nine. Another the Mages Guild + Shivering Isles and the last one is playing through MW MQ in Morroblivion. Haven't played for a few months but I know it's still there waiting for me.
Many fond memories.
