I don’t even remember all the trash games i tried to played just to delete them after few minutes.
But the ones being remembered are instead the biggest disappointments, games which were supposed to be great or were supposed to be improved sequels of great games.
In this cathegory trashcan lid medal goes definitely to REBEL GALAXY 2. I played first part like 10 times and only ever wanted more of it, but 2nd problem was not that it was bad or not (it was though), but that it was entirely different game.
Dishonorable mentions for few more:
Dragon Age Inquisition for being a solo player simulator of a boring MMO instead of a awaited resurrection of series and even sub-genre
Marvel Midnight Suns, again for being supposed to be next X-Com but in reality being poorly optimised card game
Pandora: First Contact, supposed spiritual successor to Sid Meier Alpha Centuari. Well it was spiritual in sense i wanted to get drunk on spirits because no chance to play this turd while sober.
Starfield, i don’t think i have to comment on this
Less specific but every Dune game since Emperor: Battle for Dune and probably every Dune game in the future as long as the unFuncom have the licence
Gladius: Relics of War: for a game that had so much development and DLC’s it’s still shallow as puddle. Which, along with Pandora above leds me to:
Everything published by Sltherine i played maybe except Armageddon in good way and Pandora in bad way. Somehow nearly every good idea for a game that this company make into reality turns out to be the mediocriest of mediocrest game ever.
EDIT: oh and the one i tried to forget so hard but other poster made me remember it: “X-Com” Chimera Squad. No, just fucking no, the pathetic death of series after glorious predecessor is just too much.
