Three-way tie between নিন্টেডো DS, 3DS, and Switch? xD Switch is kinda a hybrid I guess. I like the 3D from the 3DS, although the console was easier to break. I haven't broken any of my controllers before but the 3DS' R and Y wore out on me and the stick's pad flew off so I glued it back. I ended up buying another 3DS. NDS and 3DS both had a good selection of games. Switch well...its new and I know I will প্রণয় it আরো if নিন্টেডো keeps supporting it. (Hopefully they stop porting Wii U games and focus on new games. The porting is a little too much now and its getting a little annoying).
As with many old consoles, this one brought back many memories. I remember play Sonic Advanced 1, 2 and 3 on this. And, sure, it may not have had the best lighting.... but still, it was cool for it's time.
PS Vita. Honestly, I believe it has a lot of potential. Too bad it isn't really popular. It presented pretty unique functions in comparison to its predecessors. I have found quite a few titles that I really loved on it too (IT BROUGHT আরো DANGANRONPA INTO MY LIFE!). For that last reason, the PSP is a pretty close second. I always preferred Handheld Consoles আরো !!!!
