Yes, Lobster is meant to be a much more pragmatic language, for people like myself to actually get the job of making a game done :) Other languages of mine are much more research-y. Though I will say I think the type system and lifetime analysis are pretty novel actually.

I'd like to think there's really only one Lobster, while older versions are still recoverable, they for practical purposes don't exist anymore :) Have you seen https://htmlpreview.github.io/?https://raw.githubusercontent... ? That actually contains some history.
