Jak and Daxter, a series that I discovered on the PS2 with my cousin and spent many hours playing through the first game without a memory card!
The days of going through a game without even just 1 save point still haunt me to this day but it also brought many fond memories and made me realise how much pressure made progress on games even better.
Jak and Daxter is a trilogy of platform/adventure games done right. The first game is a light introduction into the mechanics and world of the comedic duo. From here, the game takes a darker turn in its sequels and the gamers begin to mature. It almost turns into GTA set in this alternate universe with the introduction of guns, vehicles and other mechanics.
I wish Naughty Dog would return to this once more and give us the sequel we deserve. We miss you Jak and Daxter.
