does anyone play psychonauts??

ive been addicted to this game and im playing the first game, even thought ive already seen a playthrough so the first one and rhombus of ruin are basically spoiled for me but i brought that upon myself ^^; BUT i have yet to see the rest of psychonauts 2 ill try not to spoil anything for myself but i am too CURIOUSS >:00. i dont have enought money right now to buy the second game so i might ask for it for christmas. ive already seen the first level and it is fuckingg GROSSSS but it's pretty cool considering the design concept. what do you guys like about the first game??
