The newer (and cheaper) model of the Acer R11 has an Intel Celeron N3160 with Intel HD Graphics 400, making for a cheap, fast, long battery, netbook-like device that can still play games on the lower end of the spectrum. I haven’t tried anything twitchy, but I would assume only older titles will perform well. On my Acer R11 CB5-132T-C1LK with an Intel Celeron N3150, 4GB RAM, 32GB Flash storage, I can smoothly play:

This should be possible on any Intel-based Chromebook. The way this works is that your device is always using ChromeOS’s Linux kernel, but you’re running a chroot (essentially a fake root file system) that contains everything needed to run software from Ubuntu. But, with Developer Mode, a script called Crouton developed by a Google employee in his off-time, and a bit of effort, you can have a low-end laptop that runs both ChromeOS and an Ubuntu Linux desktop at the same time – without dual-booting. You might think that ChromeOS cannot run games that aren’t browser-based, and by itself you would not be wrong. Update #2: A Chrome security update necessitates running a command on the Crouton script before running it the first time. Update: I recently updated this walkthrough for Ubuntu Xenial instead of Trusty because that’s what I’m using now.
