Fallout 2.
Everything about it.
The brutal combat.
The turn-based combat.
SPECIAL's action and consequence.
The dark yet humorous quests and dialogue.
The well written characters.
The unique gameworld.
The whole "post-apocalypse" setting.
The inventory management.
The HUD.
The world map travel and encounter system.
The skills.
The balance.
The weapons.
The thought put into places to have them make sense.
I can't think of a single thing besides the bugs which is bad about FO2.
But "why" I like, for example, the HUD?
Can't explain it.
It's just.... Perfect.
I have always wanted to play the predecessors of Fallout 3 just to get a little a little bit of back story, although the Turn based combat doesn't exactly float my boat, I could put up with it.
Secret of Mana(SNES)
It has a decent amount of replayability, and if you grind enough at the end in the flying fortress, it's possible to earn weapon orbs that can take your weapons from what you originally thought to be a max of level 8, to the ultimate level 9 weapons. I also have a ton of memories playing this game all the time with my best friend when we were younger, and we would both voice our characters, both during the text writing, and just throughout battles. A lot of laughs were had that way. It also has an awesome storyline that I fell in love when I was younger, and still greatly admire and love to this day. It's stood the test of time for me.
Nostalgia - how I wish I could have just as fond memories :L No game when I was younger appeals to me any more, the only game I can remember enjoying with pals whilst playing on the same couch was Halo 2 when we had no clue about xbox live and all that Jazz. As for your game that you mentioned, I looked it up and immediately saw "Japanese..." - to each their own I suppose
