Having had a C128 and a Spectrum 48K I can tell you I never had a Specy tape that failed.
Now that's impressive. I wasn't nearly as lucky, although my speccy-related failures were all down to +2A incompatibilities, even in 48k mode, perfectly good software would crash after loading.
As for the OP's question. I still say C=64 Paradroid was a far better game than Amiga Paradroid '90. (Or does that count as a sequel?)
