tis a pity indeed..
I went out to lengths to buy Race Day online since it is not available in U.K. For me, despite being a collectible game, it plays well as a "non-collectible" since as long as I had enough different cars (6 to 8 in our games), it was playable irregardless of rarity. Also, none of us are aware of which NASCAR star they may be but still enjoy the gaming mechanics very much.
This game will remain popular and be played for time to come I hope. For me it joins Netrunner as another good game, discontinued before its time.
