BF4 still, with the way things are going it looks like it will be the last remaining good BF game. The HC Conquest server I always play on is still full most of the time (64/64).
Also opened up my Steam library and played a trilogy I hadn't in years, Max Payne 1-3. Very damned fun!
I'm greatly looking forward to Just Cause 4 very soon!
Forza Horizon 4 is very good as well, but I don't think it will have the staying power as there doesn't seem as much to do. I do like driving my M4 without worry of committing vehicular manslaughter though. Looks great at 3440x1440 with my new RTX 2080ti!
