>>51430506This thread triggered my autism so here's a rundown on why DPP and HGSS have such different looking sprites. DPP has more dynamic posing as OP points out but overall is a much more cartooney take on pokemon. Notice how DP Rapidash in picrelated has a more rounded and simplistic face whereas in HGSS it looks more like a horse with a longer snout, or how Machamp in HGSS has more muscle definition and overall detail compared to DPP. This sense of realism is also why the poses are different, Machamp and Steelix have more static and basic poses but they are much better drawn and give you a greater sense of their size. Steelix in HGSS is just standing upright but in doing so you see how tall he is and because his tail is further away and gives you depth which also shows you how long he is. In DPP he's much more scrunched together, it's a more dynamic pose but everything is on the same plane so you can't really tell how long he's supposed to be, it's like they were trying to fit him in a smaller space to look more inline with other pokemon whereas HGSS wants to show how massive he is in comparison to other mons. In OP's pic, HGSS looks worse because tyranitar is doing the same static pose as other mons in this game in order to fit in, however his design is very stubby and therefore you don't get the sense of ferociousness you should. Tyranitar just doesn't look cool standing upright doing nothing because his design is not that menacing without movement, (it looks a little better in-game because you see how tall he is) it also doesn't allow for more detail (besides better dimensions on the holes) without changing it entirely. He fits much better in DDP where he can have a dynamic pose without looking out-of-place and without sacrificing a more detailed design.
TLDR HGSS takes a realistic but more static approach to pokemon sprites whereas DDP takes a more dynamic but cartooney approach.
