I'm among the small minority who has played the original sidescroller Duke Nukems but not Duke 3D. The sidescrollers were pretty amazing too though, such good fun.

This always cracks me up.
eh Justice are my favourite, then it's a mix between artists like Mr Oizo, Sebastian, Breakbot, Danger, Flying Lotus, Boards of Canada, Aphex Twin, Digitalism, Busy P (although he has not produced many tracks). Some notable mentions are Bon Iver and Goldfrapp.
Loads of random shareware games my mum used to download on to the computer for me. Alot of them were the old Apogee games, stuff like Commander Keen.
I used to play the original Duke Nukem (the sidescroller) religiously, probably the most memorable out of those games for me.
