Yeah, I mained him in Brawl as well. I would play with him, Jiggly and MK a lot (he was OP). I don't know why I liked Ike so much tbh, he was slow but he was also really powerful. I thought that he was even better in Smash 4 and I use him when playing competitively.
Yeah, I may play one in the summer, I heard that the games take a long time to beat. I also heard that a new one is coming out this year, though I'm not sure if it will be for the 3DS or Wii U. However, it's exciting. :3
