I know the PS2 is considered one of the best console ever, it certainly sold the best. But it was my least favorite PlayStation console. I enjoyed the Gamecube quite a bit more than my PS2. I also wished I would have gotten the Dreamcast, I thought about getting it so many times back than, especially when the price dropped. I've never owned a Sega system, but I still kind of regret it. I keep hoping we will get Skies of Arcadia brought back, as I missed out on that game on the Gamecube, but it looks terrific.
I'm actually right there with you on the GameCube. I think Nintendo just didn't market it right. It was truly amazing. My favorite console of the gen.
Also, it's good to see you have an open mind. Something I had to learn the hard way. Most consoles are worth owning. We only hurt ourselves when we're afraid to at least try something new. And yeah, Skies of Arcadia was AWESOME.
