My all time favourite.. probably Warframe because I have played it for thousands of hours, bit shadow warrior 2 was really fun as well. I'll stick with Warframe, just because it's free and got a super fair p2w mechanic.
Hey,
If I win this bundle, I would play Red dead redemption 2 and Forza Horizon 4. Sometimes Terraria too.
A new monitor also perfectly fits into my 2 monitor setup, I am hyped.
