Is Final Fantasy Legend on Gameboy worth it? I've read that that game's damn near impossible
No one responded to this, so I figured I might as well say something. FFL (SaGa) on the Game Boy is actually not that difficult once you know how the system works. Essentially, you have three types of party members:
Humans, who gain stats by you feeding them items. HP items for health, Attack items for attack, Agility items for agility. They're all clearly labeled. They don't use magic so you load them up with weapons and armor and they're your fighter types.
Mutants, who gain stats randomly after a battle. They also randomly gain techniques after a battle (essentially spells). You can have up to half your inventory filled with techniques, and new ones replace old ones. So they end up being your mage characters. Sometimes you can luck out and get a really good technique early, other times you don't. They are less consistent than humans but they have the potential to get more powerful quickly if you are willing to save and reset. For single-target damage humans will do better (because you can get their stats above 99 due to an oversight in the game engine) but mutants have lots of multi-hit spells, which is important.
Monsters, who stay at fixed levels of power. To get a better monster you feed them meat left by an enemy at the end of battle. Due to the mechanics of monsters you can actually get a ridiculously powerful one at a very early point in the game, but you need to be taking a specific series of steps. The results of your monster + enemy meat is well defined, so if you're willing to look up a guide you can get a lot of mileage out of these guys. However, you cannot customize their equipment or skills, so they end up being sub-par compared to humans and mutants.
The key sticking point for most people is that your power growth is not based on how many battles you fight. If you spend all your money on new weapons you're worse off than if you spent them on stat-ups for your humans, for example. Once you understand the system it's not too hard at all.
You can't like TF2 and not like Nerf Now.
