Edit: Summary: Rant about RetroAchievements being online only.

I love the idea of RetroAchievements and I used it in the past. But I do not like that the games basically becomes online only titles, if I want keep playing with achievements. Even more so on a handheld, but I also used it on a desktop PC. The moment you lose internet, no achievements can be unlocked. I had those moments (even for longer period of time like days) and I didn't want continue playing the roleplaying game, because I could miss the achievement. Then I looked what games I could play and decided to play a system where achievements aren't supported. That was the moment when it hit me. From that day I stopped using it and now I can play whatever I want, whenever I want.

They have their reasons why they don't want to have offline functionality. But I wish one could setup an offline account that will not interfere with their leaderboards, because they don't want you to cheat. Yes, that's the reason... And in fact, if you cheat, you get banned from leaderboards and can still earn achievements; you just can't participate in the leaderboards. So I do not understand why this cannot be build as a legitimate normal functionality, if they can track it!
