Stellar Conflict. Which was a name I didn’t recognise, but I looked it up because it was on sale for cheap, and it turned out to be a reimplementation/variant of Light Speed which is a game I do know about (and own, in its colour version). It’s a neat wee design which is not like the other games that I’m familiar with, so into my cart it went.
Paging @Benkyo in case that information is of interest, given How many on the Top 100 BGG...? - #51 by Benkyo (but also noting that the two games are not identical).
