Ok, so i dont know if Double fine would/could do those games, but there are games that i hope to see one day on pc, and i would like to talk a bit about them.
1A good hack and slash: the request may look weird, since Double fine in its descriptions states they focus on history. I had a lot of love for Diablo, but unlike many players, i enjoyed mainloy the atmosphere, more than the gameplay itself, and the dark/gothic background.
When Diablo 3 came, i played it a lot, but i was quite disappointed because the universe was completely different to me. I enjoyed the game more when demons were real demons from Chrsitian lore, that you explored dark crypts filled with skeletons in a labyrinth,etc.
Most of hack and slash nowadays use opened environments, rather than closed environments. I have been playing many different hack and slash but i cant find one reproducing a Diablo feeling.
I would like to see one day, a hack and slash that would be really dark and gothic,with developed and serious lore.
2A beat them up that would be as good as streetsof rage. 2d beat them up arent that many(shanks is good though), and not many of them give me as much fun as the Streets of rage. I would enjoy a beat the up where you beat punks or one where you kill monsters in a sword and sorcery universe.
While there are lots of 3d beat them up and lots of hack and slash i sometimes have the feeling to be the only one looking for games matching my expectations(its a game where you fight but atmosphere must be deep and cool).
