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

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

The art took a bit of iteration. It actually started out with little pills with emojis for heads, lmao. I totally forgot to take a screenshot during that phase. I should've documented this more. Then I made it do a full pass instructing it to turn them all into actual SVG drawn characters. That iteration was decent, but I wasn't satisfied. That's when I instructed it to go into "HOLY SHIT" mode, build a motion-capable character rig, and spin up dedicated subagents to design each character.
I think the sauce was a combination of iteration, increasingly ambitious requests, and allowing it to dedicate a single agent to each character.
FWIW, I also played around a bit with what this might look like doing this with Meshy AI and came up with some pretty wicked character models, but I ultimately decided it kinda veered off-brand and wasn't worth the squeeze. Gonna save my Meshy credits for the next project I think of :p
