What do one look out for before buying a game console, say ps3?

Why do you need a game console? Now there are a lot of computer games and games for smartphones.

I prefer computer games too. So you can get a game not one on one with TV and prefix. There are strategic games that will give you more opportunities.
I like WoW. Raid ny'alotha was released in late January. The game is very cool. But it's too hard for me. It is necessary to kill all 12 bosses, pass the tests, collect all 26 achievements. I read about mining in Ny'alotha, including pets and mounts in the guide. But it's hard for me. I asked for help from the legionfarm team and buy Ny'alotha raid carry https://legionfarm.com/wow/nyalotha_category . It's amplifying characters and saving time.
