Had three games removed from the 100% list due to the addition of new achievements: Wingspan, Where Winds Meet, and Terraforming Mars. Special shoutout to certain games:
FPS: Sniper Elite V2 + Sniper Elite 3, DOOM, DOOM Eternal
Tactics/Boardgames/Puzzle: Sagrada, Patrick's Parabox, Shadow Tactics Blades of the Shogun, Shapez
Metroid/Action: Ori and the Blind Forest
Misc: Phoenix Wright Ace Attorney Trilogy.
TO AVOID:
Talisman Classic Edition, which is mind numbingly bad for achievement hunting since the most optimal way to get them would be to do hotseat with yourself.
The Escapists, it's far worse than The Escapists 2 with the checks on your bunk and the UI is makes the whole experience so much more tedious.
For Honor: Only elite gamers are left, and short of becoming a godly player yourself, you're going to need 7 other players to farm streaks in some dead modes, and you can't predict the servers in which you're going to end up at anyway so your prearranged teams might not even meet.
