(But we do get all expansions for free anyway.)
Don't think that should stop us talking about it in hopes no one will ever get a bad taste in their mouthes like a lot of DLC these days does.
A lot of companies these days seem to finish a game and then cut some out to sell as DLC, which is one of the worst things that any company can do in my opinion.
cuorebrave's idea of having something in the game that doesn't lead anywhere untill DLC is fine, but if they finish that entire story line and just timegate it untill you have paid for the DLC i'm not OK with it.
Me i would like to see expansions for both single and multiplayer in the same DLC.
Using Cuorebrave's example, you find something in the game which will set you on a singleplayer quest that makes you meet, for example, 6 new races.
All the ships of these races also get added to Super Melee, 2 or 3 for free, the rest are unlocked when you buy the DLC.
This way people who don't buy the DLC still get an update to Super Melee and incentive to keep playing, and they meet other people who use the ships that get unlocked when you did buy the DLC. These should of course be balanced so it won't be pay to win, but people will still want to fly them and wonder how these ships and the alien races inside of them feature in the universe, so they will be tempted to buy the DLC as well.
That's my two cents anyway
