SU started out very strong on this area when they launched their covertapes. Go Bear Go is an awesome Pengo clone, plus it has a screen editor. What more could you ask for?
Bear A Grudge struck a chord with me on the music and graphics. It's a commendable Space Harrier clone, although I personally don't like Space Harrier. However, it's a really good technical achievement.
Then there's Advanced Lawnmower Simulator, which surely was CSSCGC before CSSCGC existed! You can't hate this crap game because its crappiness is the entire point. It's the home computer equivalent of a novelty song, a sharp witted novelty song at that, ridiculing the shovelware punted out by Code Masters.
Sadly, there is the utterly toe-curling gubbins that is the Electro Bingo series made up by Sinclair User. The mag turned to the 'reader bingo' tactic on their front covers, an idea copied from the UK's national newspapers at the time, to shore up flagging sales. The first accompanying BASIC game was atrocious and the next two were simply the same with more things removed from it. Definitely horrific trash. At least Advanced Lawnmower Simulator and Pathetic Pablo Bros had a self-awareness about their BASIC origin, the latter being an exercise to teach readers about the possibilities of BASIC game programming.
The outlier here is the 'remix' of Gold Mine, which may or may not have been SU's idea, but they were certainly desperate to count this supposed upgrade to what was literally an existing item on the same covertape, as part of their 'Great Eight'.
