MaNGOS ( on-Hold ) !! Cataclysm is coming !

[stoneharry]

isn't MaNGOS opensource?

You can still customise everything within mangos - it's just a lot easier and faster with ArcEmu and ascent based in general.

Think he's trying to say MaNGOS is harder to customize compared to ArcEmu

[stoneharry]

I'm very biased when it comes to emulation - I don't create servers that are remotely related to blizzlike content, hence when Mangos have more working I couldn't care less. I create a custom world, with my own game mechanics etc.
In this sort of work - the stability is increased dramatically, since it is 100% your content that you make as bug proof as possible, you don't have to depend on crappy DB's with corrupt flags/spawns everywhere or quest to be exploited etc.
