Just thinking about one A Lister - AFM. Nine years ago there were maybe 20 in the country and I got one based on having been playing one at a local venue. It wasn't an A lister then - few had heard of it. In fact, many who had  were critical of it lacking enough toys.

Nowadays, aside from some few critics (many of which would be genuine in their belief, others would be less so) it is a confirmed a lister, rapidly approaching the lofty mm heights.

Another game I like is wh2o. A few years ago a firm b lister, today seemingly on the A list.

Seems it takes time for games to be rediscovered. My personal opinion is due to the questionable stern titles (more misses than hits) collectors are looking to the DMD classics from b/w of the nineties, and up go the rankings of games previously overlooked.

What's next? Congo on the A list?
