I guess it all depands how you look at it. Ps2 is great console but since ps1 was already huge huge success ps2 didnt add much for Sony beside just continuing dominance, the same can be said about SNES, since it just continued where NES stoped. On the other hand 360 put MS on the scene as competitor to Sony and Nintendo and just another , one and done, console. So i rly think 360 is better second console then ps2 or SNES (i am not talking here about games just about importance of the console for company)
And just another note for ppl who have hard time understanding what i want to say since english is not my first, even its not my second language so if i sometimes say something that make no sense to you just bare with me and correct me where i made mistake.
