For those of you who don't understand why Minecraft isn't on PSN - it's because it wasn't made by Mojang. Microsoft payed third party studio to make a port, Notch himself said that they didn't let him do it because he would f*ck it up, so if ever Mojang happen to try make it on PS3 it probably would be a catastrophy. They wouldn't have the right to take X360 version because it doesn't belong to them - it's payed by Microsoft and made by 4J Studios. Mojang will have to make it from the begining.

Thank you very much for the answer.  I kind of figured it had something to do with MS buying it, but that kid did have a point with ram too so there is that.  Anyways thanks for the answer, much appreciated.

Given its sales pace, it never will be. Castle Crashers has had 1 or 2 sales in the 4 years its been on the market.

I thought Xbox and PS3 had 500mb of ram each

Both of them work differently.  It is why the PS3 is unable to do crossgame chat yet the vita can.  IT is also why they have problems with skyrim and oblivion dlc if i remember right.  It's a very complex piece of hardware to work on and it is why many developers don't like working on the PS3

The PS3's architecture is significantly different than the Xbox 360... 3 cores vs. 9 SPUs. 512MB of ram vs. 2x256MB of ram. That causes a lot of issues to port content from one system to another.

The 360 is far closer to an older PC in how developers approach it - which is why you see a ton of cross PC/360 content, because getting them optimized and coded varies very little. Comparatively, that isn't the case with the PS3.
