>~6624 sprite renders per car which only triples for cars where it has additional pony truck carriages and a different front and rear car
>Does not include the additional angles needed to make some new inversions work
>Does not include the spritework needed for the tracks
>Also RCT1 uses 16 angles per axis for animation while RCT2 uses 32
Maybe a flatride /is/ the way to get into this. Jesus Christ. I assume it was a lot but only seeing this now yeesh.
