Are you an obsessive gamer that has to collect every doodad and shiny object you run across? Do you feel like you haven't finished a game unless you platinum its achievements? Then, welcome. Which games do you feel inspired you to explore every nook and cranny, turn the world upside down in search of every hidden secret?
For me I would have to include:
Suikoden series - Getting all 108 stars was both a challenge and rewarding. Some were missable and time based which is a little frustrating.
Batman Arkham series - Damn you Riddler, but I enjoyed every minute of it.
Ni No Kuni 1 - I never played a pokemon game, but Ni No Kuni just hit me the right way with its monster/companion collection/training. Even had a fun crafting system. Almost 100% the game but ran out time when other games came out.
Grand Theft Auto San Andreas - There's just so much to do and explore. But that could be said about almost every GTA game.
Horizon Zero Dawn - Own the game but haven't started it yet. Heard that it is a collector/scavenger's paradise.
