Claude is still working for me on a mashup of two very mainstream games. It has had to do (and continues to) extensive reverse engineering and quite a bit of "hmm the game assets are encrypted, let me decompile it and find the decryption key". Not sure if it just refuses new projects or I got lucky and managed to avoid all the tripwires so far. I don't plan on sticking around to have it suddenly start refusing to work for me, so I'll also be switching to OpenAI once my month ends. Hopefully it keeps working for the rest of my remaining time!
Jokes on me if Codex refuses right out of the box, so I'll start low on the usage tiers and slowly upgrade as it proves it can be trusted to continue the work.
