Hello!
Here are my appraisals:
0888808.com - I'm not very familiar with the chinese market. I know 8's are good, but I think I read they don't like numbers starting with 0's... So considering also that this is a bit long, I would say mid to high &xx.
GameM.net - Brandable and the logo is interesting. However, .net hurts it and the value decreases. I would say high $xx to low $xxx. Developing it would increase the value, imo.
Best of luck!
