WOAH THAT IS A COOL DEVICE!!! That looks very very fun but yes the price is quite steep. I personally only own an Adafruit PyGamer (or two) and some Micro:bits. The Pygamer is currently running ~$45 on the Adafruit website and ~$65 on Amazon. I actually haven’t used in in a while so I’ll find it and try out a few games.
You can download a game with the device you want to put it on selected in the device menu and it will tell you if that game is too big to fit on the device, so if you have certain games in mind then you’ll want to try that out before buying the device and finding out that the game won’t fit. For example with my own very unoptimized Teeny Tiny Cat game, I can see that it would be too big to fit on my PyGamer without actually having it in my hands:
The PyGamer also appears to have even more storage than the Ovobot Xtron Pro!
