AFAIK it can only do text games, but I don't know what improvements IBM has made in two decades. The other limitation is that the terminal buffers input until you press Enter, then sends the entire screen, so only turn-based games are practical.
The buffering is a neat feature. Your AS/400 could be extremely busy (sometimes the operator would prioritize a very urgent process), but you could do a screenful of code, then press Enter and go for a coffee.

- jaak 5y agoI believe the AS/400 calls it Field Exit. One of the things I used to do for new users was remap Field Exist to Enter in the IBM 5250 emulation software. Then the enter key acted like the user expected (on a real 5250 terminal there is a separate physical Enter key located where the right control key is on modern keyboards). Explaining Field Exit vs Enter was something most users didn't get. However, they did understand Enter as like a submit button (like on web pages) and were fine selecting fields with the mouse.
