As you may have seen when you looked at Graphicool1's long-running thread, I have played the beta twice and have had the game on pre-order since the first time I played. To me, ESO feels a little different to other MMOs, which is all to the good and I like the minimal interface, compared to the likes of WoW and Rift. It will be much bigger than Skyrim, the province of Skyrim is in ESO, although parts of Tamriel will have to wait for DLCs later.
Personally, I don't mid paying a sub, as long as I get a quality game for the money. So far ESO looks good enough and Zenimax have said that it will, eventually, go F2P.
