Actually a lot of MMOs flop if not most. Even the very promising Star Wars, FFXIV and Warhammer Online flopped hard.

Edit :

I hope you're kidding when you say it's already a F2P or that it's an alpha. You have been on VGChartz for longer than me so you can't be that ne to games.

To the very vague question "What gameplay do they need to fix?" you might need to be more precise. And to be frank that question seems dishonest.

It won't flop because a lot of people will run into stores and buy it and enjoy it. But it won't be better than other shooters or games like it. It will be an average title which will be successfull over years just because a lot of people thought that it would a innovative new experience from Bungie.

And yet you JUST promised me that you didn't mean mmorpg.

Warhammer online, ff14, tortanic are full MMORPGs with subscriptions.

Destiny is so far from being an MMORPG you might as well compare it with Diablo. You'd be far more accurate.

All I can say is that I watched about an hour of an alpha live stream yesterday and I came away impressed.  It seemed sharp for a game that is three months away from hitting the shelves.  A lot of people were watching the stream and there were a lot of negative comments about the game thrown around, but the guy who was playing it said that it was a great experience.  Just from watching him I could tell his thoughts about the game were genuine. 

I defintiely want to experience the alpha and beta for myself, but from what I've seen so far I think it will be a game I enjoy.  As far as not being focused on on one aspect I think its possible for the game to not be great at any one thing, but with Bungie I think its also possible that everything about the game will be amazing and this instantly becomes one of the greatest games of the generation.

If you call 6m+ first week a flop

160 million 360 and ps3 gamers combined.
If Destiny sells to 2% of them that's 3mil units for gen 7 consoles alone.

On ps4 watch dogs sold to 23% of the user base at launch and 20% of the XB1 base picked up the game.
So by September ps4 will be around 9mil units and xb1 should be at 5.5 or 6mil.
So at launch it should sell 2mil on ps4 and 1.3 mil on Xb1. This game should be bigger than Watch dogs.

Combined that's 6.2 million copies sold at least at launch. 10 mil life time.
That's $370mil in revenue week 1.

That ain't no flop in my book. And I am being extremely conservative, as I did not take the fact that Bungie have pretty loyal base of 5-8 million fans that want in on their next game since 2011.

you people who think this will sell below 5 million copies by the end of 2014 are delusional. Impressions from IGN/GB and twitch streamers have nothing but positive (and critical) responses. Yes, it's in beta. Yes, the game you see people playing now will represent the game when it's released. There won't be much that will change.

Can't just judge a game based on a few leaked clips of crap quality gameplay (mind you, they're from the very beginning of the game. no one has seen content beyond level 8 or the other PvP modes). It's going to be a good, and coming from a PC gamer, it's a game that will push me to purchase a PS4. I'm sure the same sentiment can be said for others

Coupled with the fact that Sony/Activision is hyping it up to be the next big thing, bundling it with a new white PS4, and Bungie's knack for quality and community involvement, there's no way it's going to flop.

Game looks great.

Those MMOs are actually much closer to Destiny than any of the examples you gave. Would you prefer me to cite MAG ? Mmmh ?

So coming back to my point, a LOT of MMOs fail. And none of the games you cited are MMOs.

And you really seem comfortable with your belief that Destiny is already free to play ? LOL

because it is f2p unless you're referring to the PS+ subscription. Bungie have already confirmed they won't be charging an extra fee. DLC is definitely a thing though, which is fine in my book. Bungie knows what they're doing. Having an extra subscription is completely illogical

He is correct in stating that it's very similar to Diablo in that you have a hub where all players can meet and mingle. you may take others out with you to more instanced (but active) zones to do missions.

You'll be surprised, Destiny will sell much more than Watch Dogs
