Well I'm no expert, so please keep that in mind but from what I have learned on
ultimategamenetwork.com ... it's a three word domain, which is about half as valuable as a 2 word domain. It's long so that takes away from the value but developed could have some possibilties - the game industry is a multi billion dollar industry.
So my 2 cents (for what it's worth) is that neither of them are really that great - worth probably the cost of the reg fee without any sort of development behind them. But again, that's a quickie answer from little 'ol me. :P I would wait a bit on the more experienced domain people to get a better one. =)
