Ok I wasn't sure if I should put this in general discussion or off topic even though BG is apart of this.
Why do some old games continue to survive, ok no continue to survive might not be the right phrase. How about, continued to be played almost religiously? Morrowind, Baldur's Gate, and my personal religiously played game final fantasy tactics.
My own personal vice again is FFT, I played this game when I was younger, did every thing possible in this game. Took the main character, unlocked every class for him, got all those classes to level 10. Got him and my entire team, even characters i never played to level 99. I hunted for all the secret characters, unlocked all the special items and secret weapons. I knew the story like the back of my hand and when all was said and done what do you think i did?
Went back and played it all over again, I had my main 100% completion save and then I had several other saved files. Each play through, I didn't progress chapter one unless I was a specific class. While this might seem "so what"to some of you, but to people who may remember the game. You may remember there were some weapons that didn't even become available until chapter 3, and chapter one was the most story driven chapter out of all of them. After you met with Ramza's brother at the castle, you could only have random encounters on Madalia Plain, constantly going between The Magick City of Gariland and Eagrose Castle, and this was hell! Its early game, YOu have almost no potions, very minimal equipment and if you have to fight a entire team of yellow chocobo... yea just -bleep- your life. Add onto that random encounters don't seem to happen as often in chapter 1. When you're just trying to continue the story, they seem like they always happen, but when you have a set goal in mind they never come.
Add onto the fact to unlock classes, required certain classes to reach certain level. While classes like summoner and monk were straight forward, unlocking Dancer required a level 5 geomancer and level 5 dragoon, or a samurai required level 5 monk, level 4 knight, and a level 2 dragoon. Add onto this samurai and dragoons base weapons didn't come out until chapter 3. I did mention I played the game with literally every class and I'm not talking about unlocking them as I played, I mean I unlocked them in chapter 1 the very second I was able to move on my own. This includes mime... who requires... a level 5 summoner, level 8 chemist, level 8 squire, level 5 geomancer, level 5 dragooner, and level 5 orator.
I also did this with final fantasy tactics the lions war on psp, my very first play through, I didn't leave chapter 1 until I was a dark knight... and level freaking 47! I've done it so far, I'll share the requirements to unlock this thing. Collect 20 crystals from 20 kills (by far the most effing annoying part), mastered knight, a masted Black mag (these two were not effing east, and hands down the most time consuming; to master a class you have to learn ALL of its abilities, needless to say I got them both to level 10 before mastering them), Level 8 samurai. level 8 dragoon, level 8 ninja. Just to unlock this class you had to unlock classes like samurai and ninja who in their own right both require a low, mid, and high tier classes to unlock. Classes which main weapons aren't even available until chapter 3! Especially with samurai who requires you to have several different types of katanas in your inventory to even use its Spirit in the sword abilities.
I would do this all again in heartbeat because I am just so in love with that game! Final fantasy Tactics is a linear story based game that once you beat it, you may miss out on some secret but ultimately the story doesn't change much like morrowind and baldur's gate (yea I said it; hate me all you want) , and yet the game commands so much devotion in me, much like morrowind and BG does to its loyal fan base, but why? What is it really about these games that many of us have played a thousand times, stories and fights We've repeated over and over again with different characters and classes; already knowing what tactics will work and what the outcome will be. We know the vast majority of the game, we know the secrets and the wonders, so why do we still continue to return to them and play what we've played a thousand times?
For those of you who are actually interested, here is a map layout of the classes, as obvious the left side is physical and the right side is more magic based, but geomancer is more magic based physical and mimes are annoying a-holes. Also dancer is more magical than physical, like the bard. But unlike the bard who supports with his spells, dancer causes debuffs with her dances.http://vignette4.wikia.nocookie.net/finalfantasy/images/3/3a/FFTWOTLjob.png/revision/latest?cb=20110226011805
