This has led plenty of disgruntled Diablo III players to make themselves heard on Blizzard's official forums. While many simply voice disappointment about seeing a PC-exclusive ported to console, user SmashCrunch articulates a broader, more astute gripe: That it's entirely possible that Diablo III was built for consoles from the start.
Diablo 3 was setup to be a console game.
The reason only 4 players are allowed into a game is for 4 controllers.
The reason the quests make you walk in a linear closed circuit as opposed to big open worlds, is to keep your buds next to you on the same screen.
The reason for no skill points or complicated number crunching? To make console players happy.
The reason you have 4-5 skills on your bar at once? Very easy to use an Xbox/Ps3 controller to use skills.
The reason no runes / complicated item mechanics exists. Simply wouldn't be fun for console gamers.
The reason you can't host a named game? Auto join for console users.
The reason for achievements in game? It's popular among console / COD fans.
The reason for passive skills? Perks like Call of Duty uses. Everyone unlocks perks and uses their favourite ones.
PC gamers are just beta testing for the console release so it wont be full of bugs. That's how ActiBlizz intends to make the real money.
Also explains why the game doesn't have VoIP for Pc gamer chat.
Diablo 3 is the modern Call of Duty of ARPG's.
There are some users in the thread offering counterpoints, but it's hard not to see the truth in some of those observations.
