I really like Terraria and I played a lot with my friends.
My problem with Starbound, I have it on Steam but nobody has it from my friends :( And I think it's a little bit boring alone.

Completely agree, Terraria for me was fun because I played it in a group, Starbound may be fun, but I´m playing it alone and because of that it doesn´t come close to the fun I had playing Terraria with friends.

There's a lot of in development games arrving on GoG (most have quite high listprice)
Steam calls it early access.
I do hope this wont reduce the search for old games (there loads and loads hanging around to be fixed to work again on all new pc)

I think many gog user like fast scrolling action games so maybe this one would be something to arrive here, its way to fast and i dont 'fancy' sidescrolling games, i played these in the past (38 years ago) and it was not a success my feet went wobbly 'my stomach turned 'thats when i noticed i had gamemotionsickness which limits the games i buy. http://store.steampowered.com/app/442210/
