I never liked their games much, after Battletoads on the N.E.S this is all downhill from there!
I think they got a lot of attention for some titles that were visually pretty neat back in the mid 90s (DKc and Killer Instinct) then they pushed the N64 hardware to its limits (Battletoads was pretty impressive for a NES game back in the days too)...
But back to the game, the way Donkey Kong Country played and the ennemies almost ignored you never appealed to me, the physics of it seemed like the game was overly "simple", maybe this was me being used to gameplay focussed Sega Genesis games back in the days...
Anyway, people are very enthusiastic and look at the logo with a lot of foundness for their older titles, MS seems to want to capitalize on their purchase for the first time, so hopefully this works out well for them...
