By the way, the podcast was a great listen as always
Couple of "Games that should've been in the arcade". I have no idea what has been mentioned already...
Stunt Car Racer
Amazing racer back in the day, created by the lengendary Geoff Crammond. Loved the rollercoaster-like tracks. Would make an amazing 2+ player arcade racer.
Splat! (ZX Spectrum)
Really simple 4-way twtich game. The screen scrolled up, down, left or right at random intervals. All you had to do was keep your character from getting trapped at the screen edge.
