I've never used Blitzmax but have used Blitz3D . I really like AppGameKit Studio and have tried a few different languages over the last few years and I was finding it hard to find something better . The more I learn about AppGameKit Studio the more possibilities
I realize . I think TGC should market AppGameKit as a very good language for games and also good for other projects. BlitzMax is probably very good but not what I would call current although some coders are doing updates for it but not officially .
I would say give AGKS a go and see what you think . I think Bmax is oop and AGKS is a procedural language . I really hate oop and will be sticking to AppGameKit for the foreseeable future. It's available on Steam right now for £19.74 which I think is a really good price. Not sure what the price is right now on TGC website .
