Na don't want that. I want a decent working 2d engine with reliable sound support.
Well yes I totally agree. It seems harsh to critisize Mark because he's obviously worked his socks off to produce it.
But for basic application writing BlitzPlus already fills that gap. And as for the native Operating System GUI I don't like the idea of all games looking the same. So why not write your own user interface that fits better with the game you're writing for? It's not that difficult.
The point is, if we wanted a general language we could have used C++ and an add-on library of sorts. Myself and a few others have said from the very announcement of BlitzMax they wanted a follow-up to Blitz3D - ie simple to use but with more power - not a C++ clone. Writing GUI's and the extra work of implementing over 1 hugely successful Operating System and 2 others just delayed the product massively in the early stages.
BlitzMax is a very impressive language - but it must be an 'Advanced Game Language' rather than a jack of all trades to stand-out. For the long term, sure add all sorts of extras - but get the actual game programming features debugged and optimized first.
