Team Fortress 2 will always be my favourite game. It was one of the first games I ever played, and still love to this day even with all the bot problems. The gameplay is super casual and its fun to drop in every once in awhile. Other games I only play to grind XP, level up, and finish battle passes. It's like every game nowadays focuses on keeping you engaged with fake to do lists. This is the only game where you don't have to worry about any progression and just focus on having fun. No other game will ever replace it, I will always come back to this game.
