Tom Clancy's The Division - Gold Edition is 90% off on Uplay.
Yes, I know. It's Uplay.
All the same, it's only $10 (and Uplay, I get it), but I've heard good things about it, and apparently even solo play can be fairly fun (I'm talking about The Division, and not Uplay, of course).
Since it's the Gold Edition that's on sale, all DLC is included.
It was a weird one for me - I got it a long time after release when all/most of the DLC came out and all the bugs/major issues had been ironed out. I really tried to get into it, but after about 4-5 goes I realised that to me it just felt like a really sub-par version of something like Watch Dogs or Splinter Cell. It's like if someone made one of those games, but then added loads of grinding and fetch quests.
I think it's one of those games that would be great if you had 3-4 friends to play it with regularly. I've heard loads of people say how great the combined tactics can be as you can do some really good stuff with all the abilities and different weapons, but to me it just felt like a pretty bad third person shooter. On top of that, the difficulty seemed way off - it was either an absolute cakewalk or an impossible slog-fest. I spent loads of missions just in a constant reviving cycle or others where we just wandered to the exit.
Again, if you've got a few people to play it with it'd be a great tactical co-op game, but otherwise don't bother in my opinion.
