you will have to sell this as a website.. the domain name wouldnt be worth much.. as a website.. $500-1000
Yes it is worth something. Sim games is a decent keyword, and if it is .com with no hyphens then it is a good premium domain and is likely getting a good few type ins. I have no idea how much it is worth, but if it was mine I would not sell it without a professional appraisel or two. The domain market is a little depressed at the moment, but it is still worth a lot more than the 2K that the .co.uk is up for at the moment.
