This game is a port of the original FINAL FANTASY VII. The following extra features are included: 3x speed mode. Ability to turn battle encounters off. Battle enhancement mode.
As this is a digital game, there are no "discs" to speak of. However, most walkthroughs, including the one I used, break it down based on the original PS1 release. This is as follows:
- Disc 1: The beginning of game until the end of the Forgotten City.
- Disc 2: The Forgotten Capital to the end of Midgar.
- Disc 3: The Northern cave to the end of the game.
There are three boosters that can be turned on and used to help you beat the game more quickly and much more easily. These DO NOT disable achievements, so feel free to use them the entire time or as little as you like. If it's the first time you've played the game, you might want to go in blind and play "legit" and if you're a returning fan who just wants to experience the story and nostalgia, "cheese" it up. Your choice either way.
- Tempo 3x: This will speed up all walking, dialogue, and battle animations. Enable by clicking in .
- No Encounter: As described, never fight a random battle. Will still encounter bosses. I do not recommend this one, since you need to get to Level 99 for an achievement, and even with the next boost active you will be killed by bosses. Enable by clicking in + at the same time.
- Battle enhancement: With this, you will always have full HP/MP and unlimited Limit Breaks. You CAN still be killed if an enemy hits you for more damage than your max HP though (which is why using the no encounter boost isn't a good idea since you'll never level up to get more health). Enable by clicking in .
As you play through the game, I would suggest having this guide on hand at all times. Not only does it walk through the story extremely well, it also points out every spot where you'll need to make a decision that affects the lengthy missable Best Bromance (15G) achievement, and marks all three of the other missable achievements: Consummate Cross-dresser (15G), See the Light (35G), and Waiting in the Wings (15G).
As you play through the first disc, use Aeris as much as possible to get kills. We will want to get her Level 4 Limit Break before the Ancient Temple story event. Also try to rotate all your characters as you level up their Limit Break. Once someone hits Level 3 and you've learned all six Limit Breaks, remove them from your party to work on someone else to avoid unnecessary grinding later on.
Also, be sure to have "All" materia equipped in as many slots as possible, and use any Double or Triple Growth weapons/armor you can. These materia, when fully leveled, sell for 1.4m gil each and will go a long way toward the Coming Up All Nines (35G) achievement. Working on this throughout the story will relieve a bit of grinding at the end of the game.
Step 2: Missables on Disc 2
There are only a few other missable things we need to worry about. Be sure to get all of these as you go through Disc 2.
- Neo Bahamut materia in the Whirlwind Maze. This is needed for the Bahamutype-0 (35G) achievement. The guide I linked above mentions when to grab the materia, so again, follow that for success.
- Huge materia in Mount Corel. You must successfully stop the train to receive this item. All four Huge materia are missable and needed for the Bahamutype-0 (35G) achievement.
- Huge materia in Fort Condor. You must defeat CMD. Grand Horn to obtain this one. This battle can be failed, but the story can continue after regardless, so be sure to win to get the materia.
- Scimitar weapon in the Underwater Reactor after the Carry Armor battle. Missing this won't void any achievement, but is very helpful in doing the Coming Up All Nines (35G) achievement. It will save time in the long run.
- Huge materia in Underwater Submarine Fight. You must defeat the Shinra sub during this mini-game or miss out on this piece of the Huge materia.
- Huge materia in Rocket Town. When escaping the rocket, be sure to grab this on the way. Cid points it out, but you can ignore him - don't do that.
- W-Item materia in the Winding Tunnel during the final section of the disc. Used for the same reason as the Scimitar. Both of these items are again optional, and marked in the walkthrough I linked above.
Step 3: Complete the Game
From here, you can just ride out the rest of the game without worry of missing any other important items, or any achievements at all. There are no missables on Disc 3. Once you near the end of the game, you can either finish it and reload your save to do Step 4, or make a save and do Step 4 first if you want the A Feat of Meteoric Proportions (70G) achievement to be your last.
Step 4: Mop Up
As you near the end of the game, or after beating it, check your achievements and see what is left. There will be many things still to do, so check each achievement below for the requirements and grind it all out now. The achievements for maxing your gil and levels, as well as the superbosses will take the most time.
Aside from the lengthy bromance on Disc 1, there really aren't any troublesome achievements in this game. If you're playing legit (without boosters) it will take some extra work to defeat the superbosses, but since you need to hit Level 99 anyway, it's not too bad. With the boosters on, the game is an absolutely cakewalk. If you're new to FF7, enjoy the wonderful story and if you're a returning fan, enjoy the nostalgia!
