GC post had me thinking…
PS2 - God of War 1/2 One of the best looking visceral fun games
GC - Metroid Prime / Echoes Exploring the world was something unique and different from the stock shmups
PS3 - Mass Effect Trilogy Last of us was probably the pinnacle but Space opera takes it.
PS4 - Witcher 3 Amazing amount of content and side missions dlc were huge.
For a small group of people definitely worth the effort of setting up your own. Treat it as a learning experience if mistakes are made.
