Guys, you need to remember this is a port of a mid-90s game.
Umm, yeah, I did play this game back in the "mid-90s", actually '95 if I remember right. Actually i still play it sometimes, either the original in Dosbox or the (not so good but nice) 20th anniversary 3d remake. Anyways, the DS version is slow. Not meaning the fact that Settlers 2 has a slow-paced gameplay, but i mean the animation is choppy. Like the original being ran on a slow computer. A very slow one.
