Donkey Kong Land I, II, & III

[Charcoal]

I'm a big fan of the franchise. I've played each of the 3 Donkey Kong Country games, but what about the 3 Donkey Kong Lands?

Should I get all 3, or 2 of the 3, or just one of them?
Are they any good? They look interesting especially for a GB/GBC game.

I played Donkey Kong Land 2 for the GB when I was young. It was fairly enjoyable (though I was pretty bad at the game back then and was also scared to death from the game over screens)

I went ahead and got Donkey Kong Land 2. The frame rate is really good and I love the graphics and level layouts. The only issue is it sorta hurts my thumb to hold the B button to sprint and press A to jump, but hey, it could be worse.

EDIT: I just beat K Rool in all 3 games. Now I guess I just need to get 101%-103% completion on them.
