I dont consider my self a fan of these 3 but the playstation brand always ends up to be my console of choice growing up with videogames
5th gen = PS1, it was best console offering both 2d and 3d games. N64 and saturn offered mostly only one of them thats why they ended up having less games than sony.
6th gen = dont know yet, i used to think ps2 but it was the most ballanced generation when it came to multiplats. Xbox was stronger but the ps2 has more games in total. Nintendo released their component cables in limited quantity so i dont consider spending 130 to have good video quality while ps2 and xbox have them for way cheaper 10-20. Dreamcast same story with vga adapter its also weaker anyways and has less games.
7th gen= PS3, free online its a no brainer. Yes 360 had a bit better multiplats but paying for online makes their versions inferior. The wii was out of question, because obviously was underpowered and most of their games had only motion controls.
8th gen= PS4, sony decided to follow MSs example to charge people for multiplayer but at least their console is stronger than the others so i will again end up going for sony.
