I never had a neo geo pocket, in fact I never played a neo geo itself so no experience with that (I know is snk so there is king of fighter etc etc). However I have psp, ps vita and 3ds. If you want to buy one of this 3, go ahead and buy the psp because at this time are really cheap. I found most of my games at pawnshops between $1-$5 bucks so this is the "low price season" for this console because the vita is there. So for why you will get a psp? well, if you like rpg games this is your console. There are crimson gem saga, brave story (the best rpg on the system), hexzy force, wild arms, monster hunter (1 and 2), star ocean (1 and 2), kingdom hearts, y's (i think there are 3 games), lunar (I think there are 2 games), class of heroes, God eater, phantasy star, etc. If you like metal gear games there are like 4 games, also the god of war series is there too (2 games), power stone collection, ghost and goblin, in fact there are a tons of games that you can choose. And the best part of the psp is that you can easily mod it and play games from your memory stick, so you can buy the games that you only want to collect and download the other ones to play them. There are 4 models of the psp, I suggest to buy the old models (1000, 2000 or 3000) not the go because the psp go doesnt have the umd port to play the games and the memory stick is a newer one (m2 I think) so is a little more expensive to buy it (the memory stick itself), For the 3ds you also dont will get wrong to buy it because is a excellent console (see my collection and there is the best game to the console), the vita you can hold up, there are like 3-5 good games but isnt worth to buy one at this time.
