Frankly, I don't think this one has any business value. Or what do you think this domain would be used for an by whom? I just have to say that for a website selling PC games with a discount, these names are the ones that seem much more natural to me (didn't check if taken, and won't invest in this niche for now):
- BuyCheapGames.com
- GameDeals.com
- DiscountedGames.com
- BuyGamesCheap.com
- BuyDiscountedGames.com
As you can see, none of the domains I liked have more than 3 words, even 3 words is a bit too much in my opinion.
Good luck with your domain anyway!
