#1 - Parasite Eve - I know this game and definitely this series has it's haters, but those who love this game seem to be very passionate about it. It's not a perfect game for sure, the weapon upgrading system and menus take a little getting used to, but the real-time, turn-based combat (active time bar) really sells this sci-fi horror RPG. Boss battles are intense and the story is complex, yet poignant and not too difficult to follow. Plus, you get to play as one of the most bad*!$ female charcters ever.
PE is a great game and one I have never beaten. I have locked myself out near the end on a boss where I run out of ammo. I ended up quiting and haven't played again in 10+ years. i'd have to start all over.
Worth it! I'm considering streaming a new run of the game. I haven't played it in nearly 2 decades, and I didn't have a strong enough weapon build to scale the Chrysler Building in New Game + so I might think about making that happen.
