Sure, but technologically impressive can also mean it's impressive for the hardware it's on.
As an example, Resident Evil: Revelations looks incredible on the 3DS and I still have a bit of a hard time believing it runs on it.
I'll think of more later, but yeah, there's definitely more impressive GBA picks than Pokémon lol. I recall seeing a 3D game on it once, it was quite ugly of course but it was proper 3D. Can't remember the name.
This topic isn't about how impressive it is for the hardware but if its the most impressive for the generation of portables which you clearly know RE R isn't. If you're going to keep twisting the topic at hand, make your own topic.
Sorry for trying to make your thread more interesting. I'll go away now.
