Pro Mahjong Tsuwamono GB and GB2 (Culture Brain, 1999/2000)
These are the same game with different music and tile colors, but completely identical menus. They're both seemingly serious mahjong games. The music is much better in GB2. I was not prepared for how much I'd have to write about a gambling game I don't know how to play when I started this.
Pro Pool (Blade Interactive/Codemasters, 2000)
Another pool game. The only interesting thing about this one is that it makes you watch an animation of your cue sliding back and forth after you've confirmed your shot. I guess it's realistic, but it's kinda boring to watch that for a few seconds every time.
Project S-11 (Paragon 5/Sunsoft, 2000)
A fairly standard shmup. It has decent music and a good variety of powerups, but I don't like that you can't just hold the fire button down and it can be really hard to dodge powerups you don't want. Sometimes they just sit around on screen for ages as the screen slowly scrolls enough to push them off.
Puchi Carat (ITL/Taito, 1999)
Basically competitive Breakout. If you hit a block so that everything below it is disconnected from the top, then all of those blocks disappear. If any blocks touch the yellow line, that player loses. There's a really basic story thrown on top, but it's clearly a very gameplay-first title.
Pumuckl's Abenteuer bei den Piraten (NEON Software GmbH/Acclaim Entertainment, 1999)
A puzzle adventure game with incredibly relaxing music, but where everything wants to kill you. Those starfish? They're chasing me and I'll die if they catch up. That blue pirate up there is trying to hit me with coconuts. Even a slightly different pattern of sand is actually instant-death quicksand. A very strange contrast of theme and mechanics.
Pumuckl's Abenteuer im Geisterschloss (Neon Studios/Acclaim Entertainment, 2000)
Now the weird German puzzle adventure has moved on to a medieval setting, where you are immediately thrown in the sort of dungeon that puts switches to open the doors in all the cells. Despite a theme where it would make much more sense, this one is not full of random things that try to kill you and seems content to stick to puzzles and adventure elements.
Puyo Puyo Gaiden: Puyo Wars (Compile, 1999)
I genuinely can't believe this exists. It's a Puyo Puyo spinoff where puyos are uber-weapons that almost destroyed the world, and now people fight with them in an SRPG that is basically bad Advance Wars. I wish it was better at, well, anything, because I might add it to the list just for how weird the premise is, but I'm not going to suffer through the slow gameplay, terrible music, and crap writing to see it.
Puzzle de Shoubuyo! Wootama-chan (Kouyousha/Naxat Soft, 2000)
You have to match the different shapes in 2x2 blocks while following something close to Panel de Pon rotation rules, and all while a cursed rabbit from your nightmares does an Irish jig in the corner. It's okay, and the music is better than you'd think, but why does this exist?
Puzzle Master (Metro3D, 1999)
It's Puyo Puyo except that it's match-3, blocks usually fall in chunks of 3, and you're trying tom complete objectives that the game doesn't explain at all. I assume I had to beat the water guy in the corner, but matching blocks on top of him didn't do anything.
Puzzled (Elo Interactive/Conspiracy Entertainment, 2001)
You're the little Ditto guy and you can send out a ghost of yourself when you're standing on one of the red squares with a shape. The ghost can only move in a straight line, but if you can get it to a matching square and press A again, then both squares will disappear. I assume there must be some way of turning that was only explain in the rulebook, because the square and diamond shapes are clearly impossible to clear with just straight lines.
