Yeah.... we've disagreed on this before. I don't see how you can count an unreleased game that was sold as a pre-order and where is the cutoff? Why are you only counting LRG, SPR, iam8bit........or limited retailers. Why not best buy, target or even Kickstarters for that matter because some are backed by the same limited companies. You can't include some and not all.
If I were to add your logic and simply add LRG, SPR, Iam8Bit, VGS, NIS, Premium and Dispatch for good measure that would be 52 more and would be far more than you are showing. 986 would be the count. Thus why only counting what's in hand is probably the best way BUT as in anything collecting we can make our own decisions.
