Hmm, the only game I know I'll definitely play is Just Cause 3. Maybe Deus Ex, if it improves over Human Revolution. As for games coming out much sooner, the new Far Cry: Primal and maybe No Man's Sky, though Space Engineers is getting the planets update soon. I've got enough games to keep me occupied for now, like MGS5, Metro Last Light (which I still haven't completed) and GTAV. And of course all those Steam games I bought on sales and barely played.
Edit: I almost forgot Fallout 4. Problem is that it's a big game and I don't have the time to sink into many big games like that. I'll probably buy it later down the line when they do the equivalent to the Skyrim Legendary Edition, with all the DLC.
