I hear you on that. I work at a computer shop and a lot of times our business customers request that something like that be automated (copying files to a backup location, finding all pictures on a drive and copying them to a specific location, etc etc.) It does take a pretty long time to get everything sorted out properly (99% of the time spent is research..). But after that's done it's pretty handy. So I'll admit, batch scripts do have their uses. But imo, they're only meant for procedural, system related things, and nothing else. I've actually got (or had, some of the programs changed a bit and I never got around to updating it) a dedicated "virus tools" flashdrive that i plug into a computer and autorun starts a batch script that installs several antivirus tools to a specific location and then begins running them sequentially to scan for viruses. Which is pretty useful.
I just don't see how you could possibly write a game in a batch script and still keep your sanity.
I thought it sounded kind of nutty that someone would make batch games. I did a search; it turns out that there is a substantial base of batch game programmers who make some fairly involved looking games (for batch).
There is at least one person, SmartGenius, who has a whole bunch of batch games demonstrated on youtube.
