They did for sure. For a while the market for IM was higher than what Tron is right now.

Once the VE was announced they crashed hard, it large part because IM was such a limited release originally (and it's also a polarizing game) that the vault completely saturated the market.

Tron had to have been a larger run that IM originally so I expect a VE would affect it much less.

(and for the record, IM is one of my favorite games and I've had one since before the Vault run. I'm glad they reran it, even if I theoretically took a few thousand dollar "hit" on it - even though I was never selling it.)
