Which Living Card game, Collectable Card game or even TCG did you discover to late ie after support for the game had ended, and did you buy into it anyway?

I have just (re)discovered Traveller CCG but it looks like its time has passed and the expansions are all but impossible to find or out of my price range (mostly because of postage and tax). Now one of the attractions of LCGs, CCGs and TCGs is there is new output to keep you interested. If that isn't there would you still invest in the game and have it more like a 'traditional' game?

And is this more common than I thought, I came back to gaming as a solo player for which a LCG is a much better model for purchasing, but is the LCG model limited in scope?

I spoke to the owner of the FLGS in my home town who said that he wouldn't stock Marvel Champions because he didn't have room to have all the stock and didn't know what would sell. Given the news not so long ago from FFG about having current environments and legacy sets I think there maybe something to this. Both need rolling stock to keep afloat. So I assume that there are a few games out there that just didn't take off but were great games regardless. Have you bought into a game that relied on expansions even if those expansions were as rare as unicorn poop?

Another question is, have there been games that have resurrected after losing support from the company but kept going by its fanbase?
