Thanks for all this. I stand corrected as regards the charts and your work, I'm not going to challenge it further. A lot of the evidence does really seem to hinge on weekly magazines, so Games-X, Computer Trade Weekly and New Computer Express, so there's limited opportunity for corroboration unless you get into daily local and national news, which online is usually paywalled or institutional access only, as I'm sure you're aware. It's a shame that there's essentially no trace of CTW online. I would still go for the official UK release date being 24 June, personally. The Games-X staff only had access to the game for at least two days by time of publishing Issue 10, so that's in theory 24/25 June at the latest. Monthly magazines I've come across published a week or two beforehand only had unfinished review copies to hand. The NCE chart is admittedly something difficult to overcome as it puts that date into question regardless of what Games-X says. Is it possible that grey imports caused the game to enter the charts before the 24th, or did Gallup only count official stock? P.S. Have you ever thought about becoming an archivist professionally? I mean, did you buy all these magazines one by one and scan them in yourself? That's serious dedication to the craft!
