March is going to be one hell of a month software wise. Thought it would be interesting to predict what game will top the month of March in the USA according to NPD. 

Serious contenders are

Tomb Raider
Bioshock Infinite
God of War: Ascension
Gears of War: Judgement
StarCraft II Heart of the Swarm
SimCity

I think Starcraft and SimCity are out. SimCity could have had a chance if it didn't have such terrible word of mouth. Starcraft should be big. Starcraft II sold 721k retail copies in only 4 days of tracking when it came out but considering that this is an expansion I think it will only do half of that retail. Including digital SimCity and StarCraft will likely be bigger than the rest of the competition, but this is predicting npd.

Tomb Raider has the advantage in that it will be big on both ps3 and 360. And considering sales seem to be way above expectations and that it has a full month of sales it should do very well.

Gears of War 3 managed 2mil+ its first month so it would seem logical that Judgement will easily be the best selling game but it doesn't seem to be getting anywhere near as much hype as a typical gears game.

God of War 3 managed 1.1mil first month so Ascention should sell very well but like judgement being a prequel will likely hurt sales. It should get closer to God of War 3 than Judgement will get to Gears of War 3 though.

Bioshock 2 managed 562k on just the 360 but the ps3 version didn't even chart. Bioshock Infinite is getting a lot of hype though and an analyst has even predicted it will be able to sell 5mil worldwide. It is only going to get 4 or so days of sales in March though, so even if it is the best selling game lifetime it might not win March.

Personally I think the top 10 will look like this so my vote goes to Bioshock Infinite.

1.Bioshock Infinite (1mil)
2.Tomb Raider
3.Gears of War
4.God of War
5.SimCity
6.Starcraft
7.The Walking Dead
8.MLB the Show
9.NBA
10.CoD 

gears of war. i really dont know about the rest though

If digital sales are included, StarCraft.

No digital, Gears of War.

The Sims.

Just in the US? Gears or Tomb Raider. I think GoW will outsell Gears WW but Gears will beat it in NA near the start at least. Tomb Raider is multiplat and seems really good with a brand behind it that would've had decent sales even with a bad game so I'll say that.

1) Heart of The Swarm if you can count Digital Sales
2) Gears of War (In USA) WW not the case imo.

WW I think HoTS will be number 1, and it's a crapshoot between Gears of War, Tomb Raider and God of War.

Bioshock infinite comes at too late in the month of march imo, unless it's a bigger hit than I expected

Wow... what a packed month.

I think the NBA and Call of Duty and those staple games that always on the list will retain their spots +/- 3-4 spots. I think Tomb Raider and Bioshock Infinite will both outsell the GoW games on PS3 and X360.

I suppose Lego City Undercover on Wii U has no chance of showing up on the list... but does that Luigi Mansion Dark Moon on 3DS have a good shot of being in the top 10?

It certainly has a shot but I think it will just miss it. Too many big games coming out this month. It would need to squeeze past CoD or NBA to make it because the top 8 should all be well over 300k.

Gears

1. Gears of War: Judgement
2. Tomb Raider
3. Bioshock Infinite
4. God of War: Ascension
5. Starcraft II: Heart of the Storm
6. Simcity

Are the order those will sell in but on the NPD chart there will be other games between some of them them.

Edit: Actually I'm having a hard time deciding between the order of Gears of War and Tomb Raider
