Well I played the game for a good 3 hours or so. I would have played it more, but that was the duration of the test. I realize it's not enough time to get a full idea of what the final game will be like, but I thought I might write down some of the things that stuck out to me.
In depth character creator:
More robust than any previous Elder Scrolls game. Lots of options.
It was similar to Guild Wars 2 actually. But the stealth mechanic seemed to work much like Skyrim. The blocking and dodging worked like a charm.
As much as I've heard it was different, it feels pretty much like a standard MMO. The mission structure is the same. The feeling like you're just kind of doing the same busy work that the 20 other people you're running next to are doing. All the same.
Oblivion Lock Picking:
Some people will probably see this as a good thing. But I was never a fan of this minigame and I'm kind of sorry to see it return.
I wish I had more points to cover, but nothing really stuck out to me. It all felt very standard and though there were some Elder Scrolls affectations, it doesn't really capture the spirit of those games. Just kind of feels like more of the same.
