Sure! Who is Kuron?
Since I think your homouring me, I'll be homoured!
Kuron is a moderator at syntaxbomb, a good one too, he's probably one of the many talented BlitzCoders that have been hounded from these forums over the years, but thats for another day, as I dont want to see this thread go tits up like mine did!
Back on topic:-
As a hobbist programmer, to me, programming wise, its a good tool, because:-
1) its free
2) it lets you use a powerful 'true' OOP language to build games (And I've used C# on-off since I bought Visual C# 2002 by accident from a seller at ebay, he had it marked as VC++ 2002)
3)The language at the heart of XNA can be applied not only to games, but to general window applications as well as webpages, thats a lot for one language to do and it does it well.
4) It compiles to windows and Xbox, both dominate the home computing and console market (see Evaks sig)
5) The IDE is far superior to many IDE's out there.
6) You'll have all the 3D lovelyness you'll ever need.
7) There are plenty of reference books on the C# language, everything you'll ever need will probably only be a amazon patented 'one click' away.
8) They are working on Vista support, so I'd imagine DirectX10 will get a look in.
Its your choice, stay with Max and buy a commercial 3D Engine license, or go with XNA for free, see what happens, if it works out, great, if it doesnt, well, it doesnt, there's always Max to fall back on!
