Sony makes numerous video game platforms. They make the playstation mainly. I do not know much about this system because I do not play games but everyone I've talked to likes it a lot.
The answer you will get really depends on who you ask, as it is rooted so much in opinion. In terms of sales alone, the answer would be yes, aside from the Gamecube, all of Nintendo's main consoles...
Using a combination of starting capital (money), time and energy, and also a strong business sense with planning, it is possible to make a video gaming system.
