I thought I started a thread on this a long while ago but it didn't appear in the search results. So anyway....http://albiononline.com/
This is a sandbox/PvP/town-builder that's multi-platform (PC and mobile). No classes, skills are based on what set of equipment you choose to equip, but the catch is that it's full loot PvP so you could effectively lose your custom build if you aren't careful. Hopefully the exact gear itself won't dictate the gameplay as much as player skill and player alliances/guilds, etc.
I got an extra day off today so it seemed like a good day to try it out. They have just gone into their second Summer Alpha, which I believe is PC/Mac only right now. From what I've heard, iOS will require 2GB RAM, which means iPad Air 2 only at the moment, and likely should include iPhone 6S later this year. I suspect that's why they aren't bothering to test until the hardware catches up.
Early impressions are mixed, seems more crafting/gathering focused, but that could just be because I am so green. The graphics engine is pretty old school, I guess that's what it needs to be to support cross platform. That said, there does seem to be something oddly addictive to it. Systems are fairly simple but appear to branch out and allow for a lot of gameplay freedom. I can see how playing with a guild/friends could be a lot of fun, building up a city, etc. No idea how PvP plays out, I'm still deep in the newbie area.
I never played Ultima Online but I get the sense a lot of the influence comes from that game, so those of you old school folks might want to take a look if you get the time.
