Many over the years but the standouts for me as I think....
The BIG two that everyone will gasp at.
1. Any game in the Fallout franchise. Granted I was much younger at the time I tried Fallout 3, but I just didn't enjoy it - story kicked off too slow, back then if I wasn't blowing something up in the first 15 minutes, it just wasn't fun
*Disclaimer* I am into different games now that I am older and more patient - I recently picked up FO 4 and FO NV for 10$ combined and will be dipping into the franchise again (its been about 14 years) - hopefully adult me can be more patient. I desperately want to like Fallout, its such a staple in gaming history - one of those franchises that is on most peoples "You NEED to play this game" list. Fingers crossed it goes better this time.
2. Any game in the Final Fantasy franchise... It was a VERY long time ago - Played a little bit of FF8 but that was before I knew anything about PC's. This game prompted my first GPU purchase, a 3dFX 16MB Voodoo 3 2000 PCI graphics card! After several hours of gameplay the 10GB 5400 RPM hard drive in my 800Mhz Athlon Thunderbird based system bit the dust and the save games were never recovered. I have never picked up an FF game since (not the game's fault, but left me sour)
FF is for sure on my "want to like" list. I just need to actually commit and pick one up. FF is a genre defining game, it is for many people the best franchise to come out of Sony ever... I'd like to be able to say I have experienced it at least once. Perhaps I could dig into the FF8 remaster one of these days.
Other standouts
-Destiny 2 - this WAS a good game once upon a time. Now its just a huge cash\time suck... I hope you LOVE to grind, cause that's what your doing for the next 20 years lol
-Warframe - turned to this as a replacement for Destiny 2. Good game, but one thing keeping me from liking it - Microtransactions
-EVE online - Learning curve was just too steep for me to sink the time into, but this one is still on my radar.
-Remnant: From the Ashes... cant recall why.. I got about an hour into it and just didn't like it
-Lords of the Fallen & For Honor - Controls and combat mechanics just felt wonky on these 2
-Borderlands TPS - if you played the previous games, there is nothing new here at all... this could have been a DLC for BL2 - Do yourself a favor and skip this one (try Tiny Tina's Wonderlands instead)
-Halo Infinite: I dunno, it just left me kind of empty after I finished it, like "oh...thats it; THATS how they end it all!?" I just expected more (probably my fault on this one, the hype got me)
-Jedi: Fallen Order - just poorly optimized, fix the game and it might be fun.
-Sleeping Dogs, Outriders, Watch Dogs, Space Hulk: Deathwing - the list goes on.
