For getting the platinum in BBS, a few questions:
1) I've tried BBS on PSP and got halfway through Terra's story on Critical before I started over on Proud. If you're going for the BBS Plat, are you just trying to do everything on Critical, or are you going at it in a lower difficulty first, doing everything, and then beating the game on Critical without doing side stuff?
2) When starting a new file, what are some commands I should prioritize?
3) Is there a way to abuse the command board and meld?
1) Critical. All of it. I'll be damned if I'm going to play each scenario more than once anytime soon. I've got other games that need my attention.
2) I pretty much just meld whatever. I'm more interested in getting some abilities on my peeps post haste. However, formulas to keep in mind:
Fira(ga) + Aerora(ga) = Fission Firaga
Fira(ga) + Slow = Crawling Firaga
Fission Firaga + Crawling Firaga = Megaflare
Megaflare = good times
There's also the Mine commands (Shield, Square and Aqua's Seekers) that are fabulous for crowd control alongside Magnet spells.
You can't meld for Cure but once you've got one or two you can meld for Cura and Curaga. That and Leaf Bracer will save your ass.
3) Abuse it? Takes too long. Sure, it's great for leveling multiple commands, but you can do just as much fighting high-level enemies and using the Stitch D-Link for Double CP. However, Command Boards have hard-to-acquire Shotlocks and the Focus Block/Barrier that's impossible to get anywhere else, which you'll need if you're trying to plat. And you'll need to play the Disney Town board once and then another board until you land on a Special Panel and randomly activate 'Captain Justice/Dark'' for a chance to unlock the Pete D-link.
And early on when you're low on munny it's a great place to get some additional Commands from Bonus Panels until you manage to farm Abounding Crystals in Radiant Garden and meld for Lucky Strikes.
General strategies for winning Command Board quickly basically amounts to placing Commands in panels at every opportunity, foregoing using them as cards unless you desperately need the boost. Because every time you return to the Start Panel after completing a lap you're rewarded by how many panels you own, and because you'll get a decent GP boost if one of your opponents decide to buy (i.e., steal) one of your panels. Also seeing them lose cash whenever they land on one of your panels never gets old. Fortunately, there's nothing to lose but time by playing the Command Board. Every command you place gets CP whether you win the board or not, the only difference is how much. Except I think for stolen commands which don't get any.
I was checking my trophy list and noticed that I had several trophies in BBS, which I haven't even played, it kinda freaked me out lol.
Then I discovered my brother was playing the game when I was at work, he actually finished the game with Aqua in Critical Mode, he doesn't even play games so it's kinda weird that he just randomly did that, he doesn't even understand the story of KH at all haha.
Now here am I trying to explain him the whole series.
I think someone has a waifu.
