・You start with jack shit and get killed in a couple hits by anything except the weakest random encounter in the game, so you need to spent a couple hours grinding right off the bat before you really doing anything. But once the ball gets rolling, the rest of the game is piss-easy. It doesn't even have a final dungeon difficulty spike like DQ2 or Mother.
・There's literally no reason to do anything in non-boss battles except regular attacks. None of your magic does anything to end fights quicker, so it's more efficient to just use your MP to heal up between fights. Strangely magic is not good for clearing mobs like it is in literally ever other RPG of the era. Magic hits random targets 2 or 3 times, which makes it more useful in boss fights than anything. After a while I was holding down the emulator speed up in every fight because there's literally no reason to think or pay attention to any fight, you just wait for your numbers to beat over the monsters' numbers.
・Even in boss fights, the only useful things to do besides spamming regular attacks and having Lutz use up his one good attack spell, is to have Myau heal sometimes or cast the attack buff late-game. I could never get the attack debuff to work on enemies, and the spell that makes you immune to damage for a few turns just stopped working for me halfway through the game. Anytime I'd try to use it it would immediately wear off when the enemy attacked next. I have no idea what was going on there.
・I didn't even think about it while playing, but the game didn't have any status effects or anything. Literally the only things enemies could do to you are regular physical attacks or rarely using one of the 3 attacks spells in the game. I think a couple bosses healed themselves.
・The party balance is kind of weird, since one of your guys Tyron is some beefy chad and the only party member who doesn't learn any magic, so you would expect him to be the biggest DPS/tank of the party, but he's consistently in the 3rd place in attack, defense, and HP behind both main heroine Alisa and Myau who's literally a cat, and only barely above pure mage Lutz. His attack power did surpass Alisa at the very end, but only after getting his best weapon. He always felt like the character who was taking the most damage and getting close to dying, even more than Lutz.
・I was playing the Japanese version, and the text is only in katakana, making everything annoying to read. Did the Master System cart seriously not have space for both kana sets?
・Enemies don't directly drop money after a fight, they drop a chest that you can choose to open and get money. Sometimes the chest is randomly trapped and you take damage opening it. I can see what they're going for since Wizardry did that, but the thing is Wizardry had the Thief class whose whole point was literally just to remove traps from chests. There's no equivalent in Phantasy Star so the traps end up just being a random HP tax on getting money from random encounters.
・Chests that you find in dungeons are barely ever worth it. Half of them just give irrelevantly small amounts of money, consumables you don't need, or outdated equipment you don't need, and most of the other of chests are empty and trapped. I feel like I took more damage over the course of the game opening chests than from getting hit in battle. Myau eventually learns a spell that untraps chests, so I guess you're blinding casting it on everything or just savescumming since you can save anywhere, which I started doing in the final dungeon. (By the way, earliest JRPG to let you save anywhere, anytime?)
・The game keeps handing you dozens of one-use flashlights that let you see in dungeons, but you get an infinite use light only like 1/4 into the game, so it's just a bunch of junk you don't want taking up inventory space until you throw it away.
・Random encounters themselves are kind of jank since they can happen when you step on a new tile even if something else happened. There were several times I got a random encounters right after opening a chest, a couple times right after running away (because you move backwards when you run from a fight), one time I got an encounter as soon as I stepped in the dungeon (the dungeon BGM played for half a second before getting interruppted by the battle music), and the one time a random encounter activated immediately after killing a boss.
・Also, running from random encounters causing you to move backwards kind of has some weird jank to it. Because pressing back while in a dungeon (which are first-person btw) causes you to walk backwards. Now having you move back when running is supposed to make it so you're losing progress by running so there's some cost to doing it. That's how it works in Wizardry, but you can't move backwards in Wizardry. So in Phantasy Star you can technically moonwalk through the dungeon and if you get into a fight and run away you'll actually move in the direction you want to go.
・And the plot was really sketchy. I'm still not sure who exactly the villain even is and what exactly he was doing that's so evil, other than being vaguely responsible for some places he rules over being in disrepair, and some eltritch entity that serves the final boss was involved somehow. It feels dumb to harp on the plot of the game like this, but I never felt other 8-bit JRPGs were this light on important details.
