all right, since you sound like you are doing the teaching english in japan/asian country thing ill list both english and japanese games
This is a little about the games i have, i own them so obviously i reccomend them, but your call
RPG - English:
Legend of Heroes 1-3 (3-5)
-Generic fantasy rpg's, with a decently developed world and in game history.
-Likable, but not very standout characters
-Combat is like Lunar, where positioning matters / "wait" will allow you to move along the invisible grid
-nice music, and they look really pretty
-visible encouters
-Translation is iffy at times, but honestly not as bad as some will tell you. Dialogue is fine, Star ocean 2-ish at its worst (which was just REALLY stiff), some of the menu dialogue is just odd, like when you level up and learn a new skill it says "[Character] has [Name of skill] Learned!" which is bad, but really thats the worst of it. there are occasional formatting problems, with words going to the next line because it didnt fit in the bubble / someone didnt hit enter
-save anywhere
-timeline transfers between games with clear data / any data.
-Games are standalone (generally) but with a common world, and timeline, each game takes place in a different geographic region around the gagharv
-My only gripe is that its a bit menu heavy, in an unintuitive way, but you will get used to it.
-these impressions are pretty much all from tear of vermillion, so they may have fixed things like this in LoH 2-3
Breath of Fire III (european)
-Decent game on ps1
-Lovely sprites and character art
-loading is worse than the ps1 version, its not horrible, but it IS distracting
-game starts off REALLY slow, and it requires a bit of a grind
Monster Kingdom Jewel Summoner
-i have it on pre order so i dont know that much about it at the moment but....
-awesome music, many big names
-created by the SMT creator, and its got monster collection elements, not to the extreme of say pokemon though
-supposed to have alot of voice, hopefully its well acted
Valkyrie Profile
-if you missed it the 1st time, go for it
-menus are stretched, supposedly the backgrounds too, but i dont see it
-voices rock
RPG (Japanese):
Tales of Phantasia
-ps1 port with new sprites for your chars
-as much voice as the ps2 games
-combat is clunky but not unbearable, it is the 1st incarnation of modern tales combat as we know it
-skits will tell you where to go if you forget
Tales of Eternia
-not as much voice as other tales games for story segments, tons for skits though
-"hint" tells you where to go next so you never get stuck
-fun characters, decent plot
-2nd gen LMB combat, 3 hit combo and everything is generally alot faster
Tales of Destiny 2
-2nd best tales game ever made - awesome characters, the main char is a total moron, and hes awesome because of it.
-2nd best tales combat ever - technical, difficult, and very interesting systems in place
-battles are FAAAAST
-possibly some slowdown on the psp version that was not present in the original, but it doesnt seem to be game breaking (new videos on tales channel site)
-this game is hard, you may throw your psp
-BARBATOS
Tales of the World ~Radiant Mythology~
-minimal voice
-dungeon crawler
-neat online features
-Battles are like abyss
-crossover! tons of characters from other games + make your own character
-theres really only 2 dungeons in the game (so far)
-mormo is annoring (flying cat thing)
-you can get idolmaster outfits for your char, and switch classes at will (town)
Puzzle (eng/jp):
Lumines
-Just buy it, you'll thank me
Every Extend Extra
-part shooter part puzzle game
-dodge bullets and objects and self destruct to create a chain reaction
-limited lives
-object of the game is to get extra lives so you can keep blowing yourself up to get chains, and higher scores, and therefore more lives
Strategy (english)
Metal Gear Acid 1-2
-card based battles
-****ed up plot
-1st one has some slowdown issues, 2nd one is silky smooth
-play 1 1st, its really good, but after you play 2, you will never play 1 again
-rules are a little convoluted at 1st but once you get used to it its really deep.
Strategy (Japanese)
Super Robot Wars MX Portable:
-lots of loading due to the nature of the game, times arent awful, just distracting, and frequent
-sprite animations rule
-lots of unvoices dialogue, shouldnt matter if you've seen the shows though, most of it is banal chatter anyways.
-if you just want to play and enjoy the sprites, its really easy to get into
Adventure:
Gurumin
-adorable
-fun
-fast
-adorable
-good voices
-adorable
-cool boss fights
-did i mention adorable?
Simulation:
Tokimeki Memorial
-the original dating sim
-you have to have at least one quirky japanese game if you are gonna own a jp psp, so you might as well go with one that will never ever make it here ever
Armored Core Formula Front International
-you will spend more time customizing than in battle
-if you can get someone to play with you, AI fights are the shit
-lots of options and ways to customize both the AC and the AI

Tactical Espionage Action (kidding)
Metal Gear Solid: Portable Ops
-canon MGS storyline
-throwing guys in your truck is fun
-online modes are fun
-controls only slightly wonky, you will get used to it
-very nice looking
Beatemup:
Samurai Warriors State of War
-pretty solid, dont expect the same thing as the ps2 version
-action and strategy segments
-action occurs in mini-areas, you complete an objective in the block and you capture it, meanwhile your enemy does the same
-its almost like a board game, where you get to beat the shit out of guys in between turns
-surprisingly fun
