I think i could probably fill this entire thread with all the titles I play so I'll try and cherry pick a few.
COD:MW Remastered - Top 1% ranked Hardcore modes
COD:WW2 Top 1% SPM (legit) Top 1% 3 Catagories on Zombies speedrunning (going for top #10)
COD:BO3 - Top 1% Zombies 2 Catagories
Borderlands 2 - Going for Plat trophy, as well as all legendaries, uniques etc (nearly finished this, taken me about a week of playtime so far)
Finally playing through TLOU1 and i bought TLOU2 ready for when I finish.
Working on a FURI speedrun.
Crash Team Racing - Going for top 10 fastest run on 1 track (might expand this to other tracks.
Cities Skylines (the GF also enjoys this)
This may be a long list.
League Of Legends (Nothing ranked yet but maybe soon) - 6 Seasons (Teemo Main - Sorry)
CSGO - Can't be bothered to drag myself through ranked, have played on ~MG2+ level and am comfortable)
Have played some WoW but not for a while.
Path Of Exile - Closed Beta Tester
~300hours on Risk Of Rain 1
All the original Dawn Of War series full completion.
Rimworld, Rust, Civ 4-6.
The Halo Master Chief Collection
The entire Halo series (possibly the best fps series of all time)
The Mass Effect trilogy (andromeda doesnt exist)
Gears Of War 1-3 (great style)
Metro 1+2 (highly recommend these to any and all for a good fright but great game)
My list could go on ten times over, I've already missed out a hundred titles or more but don't want to spam too much
