Guess you're speaking about SC. If that's the case, let's see how SC pre-alpha handle against Elite.
.
Ok lets try to ask something.
Graphics: you have ships and a small starting area currently, all done by hand, does it look better then Elite's generated stuff up close? sure, is it so horribly optimized that only people with beasts of pc's can get any framerate? also true, personally I think Elite has a huge leap in graphics, because you know..its actually playable, even on very low end machines, and lets not even talk about how the visual effect bleed around. so yeah - unplayable 'beautiful' textures vs Elite very playable good looking textures just not up close...
Ship destruction + collisions: both are the same, so its not two plus to SC at best, one, and honestly, the ships in SC have quite weird designs, where Elite's are more sensible, take the aurora, if something breaks you have to eva out to fix it, Elite? last I checked, all things are generally accessable from the inside, don't get me wrong, Star Citizen's designs look good, but not sensible too much is vulnerable to the slightest thing, and as for the whole destruction thing, it is interesting, but right now it is frustrating to heck, because of everything that is interconnected this makes the ships very fragile. and Elite ships do have destruction models, you just can't rip them apart piece by piece, would it be cool to be added more visual destruction to Elite, yes definitely, does it need to be part by part destruction ripping free of the ship...dunno. But that's just my opinion.
You can walk around: yes, you can, but it is soo wonky and sensitive that at current state it isn't really a plus, add that the game is made ontop of an FPS game engine, so it already had walking around in it, it is not like a lot of effort needed to be put into doing that part, ED is getting first person at some point with walking around in ships, I don't mind waiting.
flight model: the whole insane yaw thing is the only difference, and I am not sure how I feel on that, makes it feel like a turret in space, rather then a space ship, also makes it _VERY_ disorientating and difficult to predict pilot and flight behaviour when you are flying with someone, making manning a turret or such very difficult, not to mention that everyone would technically be dead the yaw g forces since that's something the human body is very poor at handling, horizontal (left-right) g forces is what we are poorest at handling, best at front/back, then up/down.
Grouping is easier?.....if you get into the same server....still really wonky in SC in my experience, where Elite I've very rarely had instancing issues between wing members, seems to be more related to a persons connection then anything else. So yeah, experience vary I guess.
Ship modules: I do not agree, especially since modules are handled very differently on each game, at best I would say this is no points for either.
advantage for shields? really? this because you can distribute power between shield directions? granted it would be cool if Elite had this too, but its implementation feels odd on SC, again personal taste maybe.
missions are poor in Elite: Last I checked it is only certain kinds of missions that are non functional, rest work fine? they aren't fun to some? have you seen Star Citizen's missions? they are more or less exactly the same in nature at best...?
So I have to ask, are you sure your opinions aren't based around still being infatuated, hyped and such with Star Citizen, a game not out yet, a game that hasn't revealed entirely what it is, where Elite dangerous is out, and it is over the infatuation and hype stage and is in the long haul process, you know of actually being a game. It is very easy to be over excited with something not out yet, its happened to a lot of games, and it makes people not see some issues that make others worry.
Where Elite, a game that is out, yes, has flaws, but has also proven that they are working on it, sure there are unhappy people, but that is always the case. And maybe Elite isn't for you, but Star Citizen is going to have many of the same issues that Elite does, and I think it will have more because of the enormous amount of hype it is running with.
Elite had less hype, but has lived up to what it claimed it would do in my book, is it perfect? no, but no game will ever be.
meh that became a rant, in short it seems a lot of late that if a game isn't "boom bang pretty shiny, see me do this, bang bang, I'm the hero" of late, people go "that sucks!" a game is either good or it sucks and should die.
Where the heck has all the space in-between, for great but flawed games? are people feeling that entitled of late, that there is only win or lose?
