First thing that comes to mind are stocks. Im in the USA, so the only time I hear about gbp is when my broker tells me about my forex accounts. We think alike I regged investgbp.com,investusd,and investyen.com about a month ago. Work in progress. I'm starting to understand that any domain can be worth a good deal, but It needs to be developed. If you believe in it, go for it 100%
by the way, the ps3,psp,ds might be copyright problems. Sorry I dont want to be the bringer of bad news. otherwise those would be awsome.
