Quick note people: X360F (and various people I know) are reporting that the sale is better than expected. Everything (Frogger, Bankshot Billiards 2 and Hardwood Spades) half off! Get 'em while you can.
[Update]: Turns out it was a short-lived error as everything is now only 25% off. Not sure how long it lasted but the advertisment on the Xbox Live blade clearly states 25% off.

I'm still waiting for (limited time) price drops on:
Geometry Wars. Already have a great clone for PC, but would get it if it was half the price.
Prince of Persia. I want it alot, but cheaper is better. XD
Bomberman Live. It's not worth 800MSP, plus would save the points to get the expansion packs.
Assault Heroes. People say the game has alot of problems, but if it were half the price I'd buy it without thinking twice.
Crystal Quest. Not a must have, but for 200MSP it would be a good purchase.
Heavy Weapon. Already have it for PC, but would buy it again.
Marble Blast Ultra. Already have Marble Blast Gold for PC.
Space Giraffe. For 100MSP I'd get it, it's not that fun :P
Wing Commander Arena. Would get it just for it being part of the Wing Commander series.
Carcassone. Not worth 800MSP(I did buy Catan, but it's because me and my family love the board game)
Spyglass Board Games. For 100MSP it would be just fine.
Bejeweled 2. If the PC game is free, why should it cost anything? Would get for 100MSP though.
Outpost Kaloki X. Already have the original for PC, but would get it for half the price.
Boom Boom Rocket. Would buy at half price IF an expansion pack was released. 10 songs aren't enough.
Also, more from the original Xbox's Live Arcade at discounted prices would be nice.
Yeah, it's a big list, but I bet many people agree with it.

Well, for a total of 400 MSP, Frogger and Spades MIGHT be worth it now. Luckily I'll have a week to consider. =D
I guess MS listened to all the complaints, which is nice.

Shiaoran, Crystal Quest is absolute garbage. Not even worth 200 points.

Shiaoran,
Bomberman not worth 800pts?! You're crazy! Hudson's put less features in retail versions.
Geometry Wars too. We're talking about 5 bucks for a game that will give you hours upon hours of fun.
You might want to get the arcade unplugged disc. It's got Geometry Wars, Outpost Kaloki X and Bejeweled 2. Oddly enough, those are the only 3 games that I play regularly from the disc.

Dang, I should have purchased Spades yesterday. I figured this morning I would play a few games and make sure I wanted to purchase it (since I have so many XBLA games at this point I will most likely never finish any of them).
Well, back to the original 300 points is an odd number so I will be passing face.

I like Crystal Quest... Kind of. :P
I've played too much Bomberman in my life, I wouldn't play Bomberman Live enough to make it worth the MSP.
The thing with Geometry Wars, is that I know that an improved version is months away from being released AND I have a clone for PC that has more features than the one on XBLA.
I live in Brazil, buying Arcade unplugged isn't worth it, I'd be paying double the price plus paying for games I don't like(have Wik for PC, hate the XBLA version, don't like the other 2 games).
