definitely one of the best series of games for the PS2.

User Rating: 9 | Jak and Daxter: the Precursor Legacy PS2
Jak and Daxter was one of the earliest titles for the PS2 and one of the best. the game starts out with Jak and his buddy Daxter but Daxter gets turned into a small animal.. can't even remember the name of it lol but this happens while they're exposed to stuff known as dark eco. the game is similar to a Mario game when it comes to what you have to do. you have to visit different areas and collect Power Cells. you have to get a certain number of those to advance to a new area. each area has different levels. these levels require you to defeat something, collect something, play a special kind of game, help someone out, etc. doing these things will get you Power Cells. in each area, there's Scout Flies and Precursor Orbs. Scout Flies are an invention by one of Jak's female friends and you'll receive a Power Cell by collecting all of them. Precursor Orbs are mainly used to buy Power Cells from certain characters. This is basically how most of the game is with an occasional boss here and there. you don't have to collect everything to beat the game but you do have to get enough Power Cells to advance further and you can collect things that you forgot after you beat the final boss.
Jak's main attacks are a spinning type of move and I don't know how to describe the other one, it's sort of like a quick punch. these moves can help out a lot. you'll also get to use different eco powers throughout the game. you'll find small amounts of eco or fountain type of thing that gives you a full amount until it runs out. the blue eco speeds Jak up and breaks open boxes around him as well as making scout flies and precursor orbs go to him. this will also help out with advancing farther because the blue eco activates certain things. red eco powers Jak up so he does more damage. yellow eco gives Jak the power to shoot powerful blasts which is really helpful when fighting a lot of enemies at once or harder enemies. it'll also help when you need to hit things that are farther away.
this is definitely one of those games that'll keep making you mad but the game isn't incredibly hard if you're used to playing this type of game. there's also many funny parts to the game so it isn't boring.
this game should definitely be considered a PS2 classic by now and for anyone that hasn't tried the series, it's worth playing. Jak is only 5 bucks at places like Gamestop so it's worth owning. as frustrating as Jak 2 and 3 are, they're worth playing after this one.
