Final Fantasy VII - Epic whether ppl want to admit it or not and hardly a soap opera (which admitelly the next of the series did go that way)
Final Fantasy IX - Fun but nothin really special, still propably one of the best RPGs on the system (Not crap like VIII either tho)
Soul Blade - Good for it’s time, nothin compared to Soul Calibur
Dead Or Alive - Good for it’s time, good gfx for a ps one game
Legend Of Dragoon - Average and seemingly long (rather than epic) rpg with ff style of gameplay. Story has good and bad parts and battles start nice but end up very very tedious since you need to button mash way too much (lots of kinds of attacks either require rapid presses of the X button to get more powerful or require timed presses of all buttons in shen mue QTE style to be succesful)
Congrats on getting Grandia, it’s EXCELLENT (And started it’s life on Saturn but never saw an english speaking release on that system)
Other notable games to get are:
Metal Gear Solid - Better story than MGS2 by far.
Castlevania: Symphony Of The Night - MUST have like Atolm said.
Final Fantasy Tactics - MUST have as well if you even remotely like Turn Based Strategy games. The story is badly translated but it’s of EPIC proportions if you pay attention.
Xenogears - VERY sweet (Atolm seems we have same taste in games!) and gave me feelings similar to the PD series at various times while playing it. Short-ish but great!
Resident Evil 3 - Fun action game with an OK plot, you might wanna play previous games of the series first tho (or atleast the first one which involves the same main character :).
Legend Of Legaia - Fun little rpg.
Medal Of Honor 1&2 - Great console fps games, sweet for their time, should still be pretty fun n they look good for ps one games.
Alien Ressurection - Another great console only FPS which makes me wish it was made for the PC instead. Tough game.
Chrono Cross - No match for Chrono Trigger but still a fun rpg experience as long as you don’t expect it to be anythin like it’s SNES prequel.
Syphon Filter 1&2 - Fun Action games with some flaws, but still very enjoyable in a Bruce Willis kinda way if you know what I mean. Rough around the edges but fun.
Wipeout 3 - Great futuristic racing game with weapons with very good gfx considering the hardware it’s on. FAST!
Crash Team Racing - Closest thing to Mario Kart on PS One. Lot’s of fun especially in multiplayer!
I’ll reply again if I remember (and also if I feel like posting again heh)anything else worth having (there deffinitelly are more where these came from)
By the way they are not written in order of preference so check the commends on the games rather than their position in my post.
