Sigh, and the demands keep coming.
How about this: If Eva wants to do it, then let her do it. If it isn't what you wanted, then look around for something that has it. If Eva doesn't want to do it, then don't demand she does it just because YOU want it. Again, go look around for something that has it.
Maybe it would be NICE to see what Eva has originally planned out BEFORE trying to influence the content involved? Ever think about that option? You may never know. Eva MIGHT have it planned further down the road and you can get to it. But trying to reach the content before Eva has plans for it can result in making too many mistakes along the way and basically ruin whatever Eva had originally planned all along.
Sorry, but whatever YOU are looking for in a game? Well, there are enough OTHER projects to keep you busy while Eva works on what Eva WANTS to work on.
