Has this been suggested yet? I know, it looks like ass but despite its limitations it garnered quite a community over the years. Also, it can be seen as the proto-Unreal engine, or proto-Mario Maker as the best thing about it is that you can code up little scripts for its objects and make pretty elaborate maps; even today it’s not dead.
Who knows if it’s fun to play and create stuff but might be worth a shot.
This is a game I love. I have such great memories of my dad bringing it home. Exploring it. Discovering a built in editor. Inviting friends over to build levels. Writing in to Epic and getting some free swag. Great stuff!
