For pre-orders, I'd appreciate it if they are only included if releasing in current month. It gets confusing for me, and increases the odds of double counting if you list it a second time next month when the game unlocks.
Some of the ones I listed are, in fact, pre-orders (specifically the Limited Run or Super Rare games, etc. - but as you may or may not know, those are guaranteed pre-orders as you are FORCED to pay for them in advance) - I do have my own spreadsheet though (and I've been tracking which ones I've posted here), so the chances of my posting a duplicate are fairly small. I just included them all, as it was easier to maintain my sheet and noting which ones I've reported here, and which ones I haven't... ...hope that's alright!
