ShiftySatchmo The Secret World.
Its probably the most original and interesting MMO out there, as far as storyline. If you are not familiar with what its about, it is set in modern day, our world, but the premise is that every urban legend and conspiracy theory that you have ever heard of is true. It is a crazy mix of typical MMO hack and slash, with puzzles that you actually have to go out to the real internet and look up real websites to solve.
I played the ENTIRE base game solo, at my own pace, and had a blast. The base game is on the “end of autumn take my money” steam sale right now for $8.99 and you don’t have to play anything else, unless you want the DLCs.
Katsuo I haven’t got around to it yet, but I’m hoping my new 1070 will fix all the issues I had with running ESO, and I can actually play that one!
