1983 Cascade Games (UK)
A curious chapter in the Spectrum history was the infamous Cassette 50 with 49 different games (49, 50... ehm, why be picky, right?).
The authors were mostly anonymous kids, paid just £10 for each game and never credited.
The games are chunks of crappy software, funny to look at, if you like simple BASIC games, but otherwise useless, so don't waste your time, if this is not your thing.
For me 'Spectrum Cross' is still the best game of the bunch and better than a lot of Frogger clones out there.
Alien, Muncher, Ski Run, Voyager, Space Mission, Breakout, Crusher, Cargo, The Race, Galaxy Defence and Blitz are all crap but the best games in the pack.
I guess the best thing about the compilation was the included completely free, breakable plastic calculator watch. Niiiice!
