Not a great year for me but my top three are as follows (unlikely to change either given what remains for the rest of 2016)
1. Dark Souls 3 - Put 120+ hours into this, and still feels great to just pick up and play. Challenging, some great boss fights, and some very nice areas. I even liked the swamp and catacombs.
2. Uncharted 4 - Wouldn't be in a top three most years but this year there's little to choose from. Actually this turned out better than I anticipated. Started slowly, and the last few combat-heavy chapters dragged it down a little, but chapters 6 through to around 16 were almost perfect. Oh, and it looks gorgeous too.
3. Forza Horizon 3 - Love this series, and this one is the best of the lot. Put many hours into this one too, and I just never seem to tire of it. Again, gorgeous looking game; especially on PC, and there's simply a ton of stuff to do. Enjoyed every second I've spent on this.
Not much else has grabbed my attention, but shouts to Doom, Salt & Sanctuary, and Ratchet & Clank as those were easily the best of the rest. Gears Of War 4 could have been but the campaign was over way too soon, and I don't care for multiplayer.
