I'm 27, been gaming since the days of arcade and bought Nintento when it was released, then SNES, then PSX then DreamCast. When I got my PC 2001 and never bought PS2, Xbox, Wii etc, cuz I enjoyed multiplayer games like Star Craft, Half Life 1, Ultima Online, Star Wars Galaxies and a lot of F2P MMORPG far more, anyways.
I've played most single players with joy over the last 2 decades, but in recent years I cannot see myself playing some of the most popular, top rated games. So that being said I have not played any single player games and cannot find a good reason to do so.
Games I've enjoyed a lot over the last decade were Ultima Online, Star Wars Galaxies, Star Craft 1, World of Warcraft (Only do arena on it now, but thats gonna be over soon cuz Blizzard is doing nothing to stop MMR abuse and win trading)
Planetside 2 feels meh. 3 factions with endless struggle for territory and dont feel I can do much impact alone in that game. Then hacks and players who use multi accounts to ruin the gameplay experience just adds further bump. So thats out of the picture. Popular FPS games like BF3 are not more different for me than CS or HL. Endless FPS without any greater picture, just temporary fun and go kill each other and repeat.
Anyways, I can go on forever or why I am struggling right now to find one great game to play (and I've missed 95% of PC games since 2007) So I hope the community can give me one good reason why there is one game out there that doesn't feel more of the same what I played over the last decade. Xenogears, Suikoden III, FFVIII were some of the most memorable single player games I remember playing with such engaging and serious story, great characters, difficult yet great combat, music and a lot of things to do beside go there, complete that quest, then go do that quest and predictible narrative.
