OK, so I have a few thoughts on this subject and I'm going to be as honest as I can. I don't agree with the argument of favouritism, this isn't as much a statement from Frontier but instead as myself and a gamer. Allow me to explain.
Let's look at all the groups that have their own decal for in-game activity. Distant Worlds, Fuel Rats and the Dangerous Games finalists. Any other decal that people seem to be suggesting that is in a folder is not in the game so we should probably not be jumping to conclusions about why they have one or details about how they will be used etc.
Distant worlds not only had a 1,000 man expedition to the other side of the galaxy, they also engaged the community in Elite Dangerous and the general gaming community so very much. Being at the top of reddit gaming for example. We felt that it would be a positive step to reward community groups who have outstanding achievement and effort with a small in game reward. Why not someone else? Because the decision was made at that time, it has to start somewhere. But this was something that (as we are seeing) we are able to do more of over time. We also tend to give these for one off activities rather an on-going decal for a group because of the admin tasks associated with it.
Fuel Rats, Not only did the Fuel Rats have a similar amount of effort and fame in-game and out of game. they had 10,000 rescues, the had their CG AND they took the charge in fuelling Jaques to make his jump which is now seeing the first steps of colonisation.
Dangerous Games: All the finalists had thousands of members who took part and the level of time required in the CGs was HUGE. Remember that any group could have taken part and put their name forward and we also informed people before the end of the games so any player could head out and get the decal if they wished.
Obsidian Orbital which you mentioned as an example was voted for by the community, we didn't pick it. But this does highlight exactly why it would not be possible for Frontier to select which groups should begin the colonisation out in Jaques. Sadly there will always be calls of favouritism and so we need a more open system which the community as a whole can pick.
There are a few reasons why I disagree with this way of thinking. First of all is the idea of "Frontier shouldn't do something to recognise efforts in their community because they are showing favouritism". I fundamentally disagree - I feel this is a perfect example of someone taking a negative view point on something that should be looked at positively. It’s really easy to look at something negatively or pick holes in something, it’s far easier to criticise than compliment, but that way of thinking only leads to us doing less and less. It truly is immobilizing. We need to look at how we do more to be a positive influence and to positively affect the game and community.
How many other games do this? Aside from the fact that companies recognise their community through promoting people, groups and content ALL THE TIME, if they aren't doing it we should be proud to be leading the way. We should be saying "how many games have this level of recognition and involvement with their community?"
These groups aren't the first to get a decal, they won't be the last. It's not about favouritism, it's about opportunity. We have the opportunity to do something small but cool (I’m a poet and I didn’t know it) for some players, we should do that. We will get the opportunity to do more cool things for more players, we should do that too. We couldn't sit there and offer every group a decal, the amount of work would be far too much to do in one go.
I would also say that your point about "Why should we need to cosy up to Frontier in order to get our stuff in the game" is also flawed. For me this isn't about sucking up or worming your way in. We want to work with groups, video makers, content creators, people that run events and anyone who wants to make content (in game or out of game) that people enjoy. If people are passionate about making content then we want them to let us know and we want to work closely with them. That's not a negative, again, that is a positive. Working together means that we can promote events that players want to take part in, we can help new players in the game get connected to communities and make new friends and we can help connect groups creating their community content together so they can make more of their events. You don’t have to be involved with Frontier but are Frontier (by that I mean the CM team) going to be able to help promote your event better if you are working with us, talking to us and telling us what’s going on, course we will but that is definitely not having favourites.
TLDR: Let’s not make this a negative, it’s very easy to slip into that mode where we find faults in things, some people more than others. Constructive criticism is fine but we should also be positive about the fantastic community we have, people I am truly delighted to spend time with every event or meet up, and we should celebrate the amazing people surrounding Elite.
