I started with DGC, it was a great set of components. I really wish they hadn't stopped workin on them. Since then i've been using DelphiX with TurboPixels 1.2 (They both work together great.) with great success. The stuff i'm doing now is a lot of 2D and 3D together, and the bitmap font support and wulines from TurboPixels is invaluable. Keep an eye out for Omega, it's almost there, but not quite. (I dont think it does D3DRM or D3DIM yet AFAIK)
