I define whether I like a console or not through the evaluation I personally make. But I don't know if that's success if I enjoyed a game console.
Having been a fan of Sega for a long time I've learned that sales and financial success determine whether or not the flavors you enjoy will remain part of the equation in the future. I can appreciate a variety of games and consoles that I do not consider successful.
I think there's something to like on all systems, these days I usually go for the system with the best games that have already come out, rather than the console that has a good lineup. That kind of thinking is really yesterday for me. As far as the metric of success goes, it's really whether or not something will continue to be made, or whether it's gonna be changed or stopped, what determines that are sales. If something is selling you can look forward to more of it in some fashion, that means it was successful. I don't think personal enjoyment necessarily plays into that, there are a number of different things to enjoy.
