I have good memories of Block Ball, though from what I recall, it wasn't quite as great as Kirby's Pinball Land. I hope that one is next!
I picked up Kirby's Pinball Land at a local shop for a dollar last summer and played it for maybe 15 minutes... Is it really that good? Maybe I'll give it another shot. I'll probably pass on Block Ball though, I'm waiting for KDL2.
I'll definitely download the Rayman demo, though I won't be picking up the final release since I already have two copies of Rayman Origins (360 and Vita).
Of Kirby's Pinball Land? I don't. Thanks for the offer! But I don't really carry my GBA around with me, the appeal of an eShop version would be a) saved high scores and b) always carrying it around by default.
