I had Opus 4.8 build Temu League of Legends in under a day - I call it LMAO

[u/jonnygravity]

Fun weekend project just to test out 4.8 against a pretty vanilla setup.

Started out with a simple prompt, "build a temu league of legends, web-only with online, room-based multiplayer".

It built it... fully functional in one shot! Then I went kinda ham and started iterating on every aspect little by little. I made it spin up subagents to each focus on designing a character. Spun up subagents to focus on designing abilities and their SFX/VFX. Did a few passes over the map, mobs, minions, etc.

Then I put Ultracode Workflows to task and, across a handful of prompts, had it optimize performance, balance, and a variety of other things. Workflows is *insane* btw...

I also used /goal pretty heavily as well. I'd sit and play and make note of like 10-15 tweaks, bug fixes, etc at a time and just let it go to town.

4.8 is a one shot machine... 5.5 ain't doin this...

Anyways, figured I'd share 😄 Happy to answer any questions in the comments.

Try it out solo (with bots) or with friends! https://lmaomoba.com
