Thanks to all you Pokémon People, for trying to help me. I really like the chart, which is a great mixture of "looks super useful" and "I have no idea what it means". If I'm reading it right, it's saying that fire Pokémon do lots of damage to bug Pokémon. I'm stuck against a meteor enemy, which I'm guessing is a Rock creature, so I should use a Ground or Grass Pokémon.
Is this information in the game manual or something? Or did people just figure out the "which creature beats which creature" rules, after playing over and over again?
I hope that the modern Pokémon games come with this information. Like, at the start of the battle, you get a mini status screen which says, "Your opponent is a Level 4 Rock type! It's weak against Ground and Grass types!" And that way, you can more easily pick which of your five characters is best equipped for the battle. They've got something like that in Fire Emblem. It helps a bit. Or at least, it lets you know ahead of time that Character A is useless for this particular battle, so don't even TRY using them!
I will get back to Pokémon next year, after Winter Break. My channel gets way more views than normal, during Winter Break, and I need to capitalize on that by doing walkthroughs for popular stuff. Pokémon seems popular enough to continue the walkthrough--it's my most popular RPG walkthrough to date--but it's not popular enough to justify doing it during the busiest time of the year, when I get the most views, and advertisers pay the highest rates. I need to try something more popular, a walkthrough that gets views in the thousands, not the hundreds!
So Pokémon is on hold until next year, at which point, I'll check the viewcounts and decide whether or not to continue it. I'll be doing the same thing with Miles Edgeworth 2, Case 2, which is debuting next week.
