A friend of mine had Race n’ Chase. It was excellent but I do remember the cars being broken most of the time.
The spoiled kid in our class had TCR. A nice bit of kit until one of the race cars got slower relative to the other, at which point all entertainment value* was lost until you introduced meths and matches to the mix. I also remember him throwing a massive “benny” on the toy aisle in Presto in order to get an Airfix Starcruiser. I stood there and watched in horror with my parents as he did the complete thrashing about on the floor routine. Once the display had finished and he’d got his toy my dad told me to go and pick a kit. I selected a Mitchell Bomber that hung from my bedroom ceiling for many years. The half built Starcruiser was destroyed in a blaze of meths and air gun pellets about a week later.
Another spoiled mate had Chutes Away. It looked ace on the TV adverts but was in fact a massively crap one trick pony of a toy. I’m glad his birthday was before mine as it enabled me to test the latest kit and give feedback to my mum, dad and Father Christmas.
*Scalextric, analogue not the new fangled digital nonsense, requires a good deal of skill and guile along with a lot of track. Me and the boy will happily spend an entire wet Sunday racing. You do however need more than 50 cars for the sake of variety and at least 80ft of track so you can get some complex bends built 😉
