Welcome. Yes we need 3D coders. That is something which is missing I think. Someone that could port newer versions of Armagetron, BZflag and other cool games out there.
Also you should note that Amigaworld is a splitting loving community. Many have jumped to AmigaOS4 or MorphOS etc. But both of these systems meets at AmigaOS 68k emulation. Though, you cant play standard Amiga games without a emulator like UAE on these systems.
So here you have them:
Classic Amigas: Amiga 500 -> 4000T + CDTV and CD32
Nextgen Amigas/Clones: AmigaONE + Pegasos.
Out of this world but still counting: AROS :- )
Classic Amigas runs AmigaOS upto 3.9 but can also run AmigaOS4 or MorphOS if PPC cards are added to A1200, A3000 or A4000 systems.
Nextgen Amigas/Cones are PPC computers that runs nextgen versions of AmigaOS. AmigaONE runs AmigaOS4, while Pegasos runs MorphOS.
Out of this world as in AROS :-) is a open source amigaos project. Runs on mostly x86 and later on also PPC hardware. At the moment, I dont think that AROS can run AmigaOS 68k software.
Well, welcome anyway. As you can see, you have several options. Just dont fall into the gap by getting an Classic Amiga thinking it will run Quake III etc in great speeds.
