8 years ago, I mean I suppose that some people working on SW:TOR could be helping too but it that's a bit different then the multiplayer they are shooting for in Mass Effect 3....
Alright, apparently you are somewhat new to Bioware games.They don't need help with multiplayer games.
According to people who have played the ME3 MP, no, no they dont.
Besides DA multiplayer would just be mashing the awesome button until an enemy dies. Because DA is now a hack n slash.
Shattered Steel was a team deathmatch and co-op. BG 1 and 2 multiplay, well you can see people skipping dialogues everytime, then go for hack and slash and spell tosing madness. I'm not seeing the issue with these sort of multiplay.
That being said. Everyone old school was hoping for the phenomenal NWN style multiplay, but apparently it's not happening. Would it be bad to at least have some IWD, BG, Shattered Steel style multiplay? The entertainment business has always been about making money, SP, MP or story driven whatever you want to call it, they have thousands of employees to feed. You want them all to be artist and eat dust for you? Get real.
PS: Skyrim's future patch for PC is about to be something very similar to NWN it seems.
