I played SoM for about an hour this morning. The lack of an inverted camera is causing some issues, but otherwise it's alright. I wasn't expecting it to be quite so open, honestly. They just kind of plop you down and you can do whatever you want. So far it very much feels like it's about killing orcs and nothing else. Hopefully that sense fades some as I get further in. I've done a few of the quests available, including one story and a couple minor quests. Killed off one captain, and another escaped. Right now the combat feels a bit dull but there's a nice big list of upgrades to dig into that should help that a lot. The focus time for the bow really needs an upgrade as right now it just gives 1-2 shots and then is spent.
Combat feels quite a bit better than AC (I've played up to 2, just to add that disclaimer) as far as fluidity goes, but at the same time feels super super easy. I'm sure it'll get more challenging, but right now I think I've been hit maybe 2-3 times out of the occasions I've waded into a pack of orcs. Even when completely surrounded there hasn't been a challenge at all. That's a big step down from the way AC handles being surrounded, because even though AC can be frustrating at those points it feels a lot better than to just curb-stomp 5+ orcs.
Again an AC comparison...I haven't spent too much time climbing yet, but oddly this feels super-simplified in comparison. In AC you have to have something to climb on. Ledges, gaps in walls, etc.. In SoM it just feels like you can climb anything and the game just pretends it makes sense. I need to give that more time, though.
So far I'm not liking it as much as AC2, but again I think the combat will get a lot more challenging further in and that the combat will open up and become a lot more fun as abilities and runes come more into the picture. The nemesis system isn't something I've run into much so far and that should help quite a bit.
