http://www.siliconera.com/2012/06/17/god-war-series-worldwide-sales-show-god-war-iii-at-the-top/ and this was in june 2012. GOW 3 has surpassed 5 million. I'll trust sony's numbers on this one.

lol i like your deflection. But even though you are trying to make a joke, you have a point. 

Which IP brought in more $$$$ this generation? Guitar hero was a multiplat, and also a annual release. So really, its no contest. I know it sounds crazy, but "ganging up" is a viable tactic. It shows how much people are willing to come back time and time again and fork over their money. 

If Halo is a bigger franchise than GT soley based on $$$$ because of more games is gen then Need For Speed is bigger than GT.

Compare GT5 to any single Halo game in total sales. 

Comparing random IPs isn't getting you anywhere. The question is what is bigger.....$$$$ is the only logical way to determine. Offcourse Need for Speed is a bigger IP....it too is multiplat and a annual release. 

Your argument is referring to 1 vs 1. The major flaw is that it isn't the full picture. You must compare all games, as is the thread title. I use this gen only as it is current and gives a accurate picture of current levels. That means comparing every GT and every Halo this gen. 

You all forgot one important fact. This gen only one gran turismo game was released and that was gt5. Gt6 don't count yet. How many halo games were released this gen? I think halo 3, halo reach, and Halo 4 and this is not counting other halo game during this gen. Of course halo sells better. It's 3 different halo games vs one game this gen. 

Halo is very popular in the United States but its only a niche in other countries. Gran turismo is universally popular worldwide. They have a reality show too  GT academy that people all over the world compete. 

Frequency of release has nothing to do which IP brought in more $$$ to MS and Sony.

This sin't supposed to be fair....its business. 

Sorry I just disagree. Need For Speed isn't a bigger than Halo or GT. 

If it's the multiplatform that is bugging you I will (not that I want to) compare sales of GT5 and the last combined 4 forza games. Adding up the last 3 or 4 Forza games will give you a higher number than GT5. So that means Forza is bigger than GT5? No 

If the only logical way to answer this was by $$$$ and number of games this gen... then the thread would never need to be created because the question was already answered before it was asked. 

And by that logical way of thinking. Almost any game in the last 5 years is bigger than Half Life. Aliens CM is bigger than Half Life

You can't argue with numbers. You are on vgchartz. Look up the total sales of Need for Speed this gen and compare it to GT sales this gen and tell me GT is more valuable. lol you can't. 

Your Forza example is very wrong too as GT5 isn't a loner.......it has GT5:P and GT PSP sales. IP sales means ALL games. GT as a IP outsold Forza as a IP this gen. Sooo that point too has been debunked.

Your third line can only be answered because many people don't see this as a business question. They answer with their emotions and preferences when this is a pure industry and numbers question. You are one such example that has much trouble grasping this concept with the Half life comment. Sure Half life has a great following and buzz....but actual sales this gen are lacking. Thats Valves fault, not the IP mind you. 

It's pretty hard to distinguish. However, personally living in the United States, I would say that Halo is a bigger franchise to the public eye here. It's far more of a household name and generally more well known. Halo is somewhat of a cultural revelation among a lot of youth here. I don't believe Gran Turismo has that status (Anywhere). With that being said, it's still very hard to determine.

From an investment standpoint, there has to be concern over the continual milking of the Halo franchise and how it will effect the long term growth of it, as well as another company taking over the Halo formula and trying to make it work. If I were investing, I wasn't so much concerned with Halo releases on the 360. The basic engine and fundamentals were already there. It's the future of the franchise, post 360 that I'm concerned with. Building a Halo from the ground up, will be a far different task than building one off of pre-existing elements on a system with a not so secured American hardware strong hold. However, Halo DOES exist in the hot FPS market and it's literally the primary Xbox game.

From a global popularity stand-point and ability to hit a portion of every market? Unquestionably, Gran Turismo. It's the Racing Sim on consoles and the sales it had this generation just continue to prove it. If the PS3 were more successful in the United States, it would have easily sold 12 million+

I'd say it's just too early to tell. Gran Turismo has longevity, certainly hasn't shown much drop off in terms of selling power world wide, caters to more markets in more locations and sells well despite being in a very limited genre. Halo on the other hand has had more short term success with increasing sales, albeit with a far higher marketing budget but it's success resides primarily in one region and one region only and it is existing on the most popular genre existing today.

He's wrong that Halo is the best first person title ever and you are correct that Gran Turismo is relative in terms of the comparison. However, it's not black and white by any means. Personally, I'd say Halo is larger because I have a bias towards FPS over Sim Racers and I live in NA. However, I realize that someone could live in Japan and love racers far more than another run of the mill shooter. So it's negligible.

Ok let's compare. 

Gt5 11 million so far

halo 3, ~11 million sold

halo reach 10.5 mmillion sold

halo 4, 8.5 million sold

halo wars, 2.5 million sold

so you are saying it fair to compare 4 halo game sales number to one game sale numbers? Yes halo bring more money to ms as business in business perspective this gen. "Frequency of release has nothing to do which ip brought in more money to ms and Sony. This isn't suppose to be fair...it's business" if this is the case gran turismo is the bigger ip than halo. Gt series sold 70 million and halo series 50 million sold. Gt is the better business. Yes gt been out longer then halo but this is business... It's not suppose to be fair.
