Could be almost ideal to play a lot of indie games!
I can imagine something like FTL: Faster Than Light, or Hotline Miami running just fine on it.
I got Tales of Maj'Eyal running on it. It's like- a native linux game or something. I'd never heard of it, but it's pretty fun.
Why do you have a chromebook and not a windows laptop? Windows Laptops are quite worth the higher cost because they are more practical.
I have a chromebook for watching youtube and browsing the web.
Windows computers are good for general use. But since I had an awesome gaming PC when I bought this chromebook, there wasn't much point in shelling out extra money for a laptop with windows on it.
Also, I feel safer browsing the web w/ a cheapo non-windows laptop. Less chance of viruses, malware, etc.
