Two desperately needed pieces that in at least half of the older space sets are:
3839(a)
4081(a)
There's also 3298p90 which is a brick with a print on it but it is used in more space builds than a lot of other pieces period, nevermind that it is also the single most missing brick of those missing on its own... there aren't even groups of different prints on the same brick that add up to as many... but it is the "Saturn" space logo used on all the old space stuff on a long wedge which was used for almost every vehicle with any sleekness! :) I understand if you don't want to put it in for consistencies sake but it's kinda important.
I also wondered if the three classic space minifigs might get the few remaining pieces of them added? The Red, White and Blue space minifigs were the only three space minifigs for a long time and since they are just colour varients there is just their helmet, "Saturn" printed jersey and face (apparently the standard smiley face is missing in Bricksperience??) to get them added! But again, if, for consistency you'D prefer not...
I've a spreadsheet with many more missing pieces but I've not the time to get all the numbers into here atm... will edit with them later.

Thank you if you are able to respond :) and thank you from the bottom of my heart if you able to fix these and for coding such a neat little concept game that could last for as long or longer than Lego!! :D :D
