Why is there conflict? Two fundamental reasons:
- Players have difficulty understanding/respecting/sympathizing with motivations outside their own...
- SD cannot competently balance the game, especially while adding new content...
The first problem is the core difference between the two groups while the second problem explains why such differences result in conflict...
Let us look at the first fundamental reason....
SP guys are not playing against a challenging opponent...as such, they (the human) can still easily win despite using "poor" strategies or underpowered elements...overpowered elements like phase jumping orkies isn't as problematic in SP since a human player with superior thinking can outplay the AI...additionally, SP guys are playing casually...they don't have as of high expecations for game balance and aren't as likely to throw a hissy fit when things aren't perfect...
MP guys are playing against other humans...while not all MP guys have to win, the point is to try to win...this ultimate goal inherently means one must adopt only the most successful strategies, even at the cost of sacrificing diversity...that the same ship types have to be spammed may not seem fun, but spamming 2 ship types is more fun than building whatever seems "cool" and getting killed in the first 15 minutes...
Quite simply, the SP guys are in it for the immersive experience while the MP guys are in it for the strategic challenge...it is rare that a well-implemented game change will benefit one experience at the cost of the other...however, it is also rare that a game change beyond bug fixing will enhance both experiences...
In general, adding content predominately benefits the SP experience while balancing gameplay enhances the MP experience...
This is where the second fundamental reason comes into play...
Because SD is not particularly good at game balance, it is difficult for the company to both add content and balance gameplay at the same time...as Monk has pointed out, this leads to a questionable assumption that parts of the community must "compete" for SD's attention...not only must your feedback/request be good in its own right, but you are seemingly forced into either being ignored or arguing why the other group should be ignored...
This competition, or illusion thereof, leads to hostility...to make matters worse, not only is the other group one with different interests, but they are interests that are hard to respect or sympathize with if they aren't your own...the SP guy cannot respect the arrogant jerks who do nothing but play on ICO all day while the MP crowd cannot respect the stupid noobs who don't know what they're talking about and contribute nothing but nonsense...the groups simply cannot contend with each other, leading to stereotypes, hostile bashing, and animosity...
To make matters worse, SD actually does listen to the community every once in a while, and no one knows for certain which parts of the community SD listens to the most....as such, MP guys have a vested interest in tearing down and debasing "trivial" or "nonsensical" suggestions lest it be implemented into the actual game...so, even if SD had unlimited time and resources, there's still the need to dismiss bad ideas or suggestions..
Since it doesn't seem like the devs actually play the game competitively themselves, it seems reasonable that they must take much of the communities' feedback on faith...and what happens if the community disagrees? Each side has an incentive to tear down the other's credibility or position in order to further its own agenda...
