riot games would be a bit difficult, but i think a valorant username checker is possible

You are right @jaduplansti valorant can also be a good module to be set in gaming/ That's a popular game I guess.

Thanks everyone for the discussion!

Since @jaduplansti added the Valorant username validation in PR #24, this issue is now partially addressed. Riot usernames in general are tricky to validate, but Valorant coverage is a good start.

We can consider the broader Riot Games username validation as a potential future enhancement.
