What would be the aspects of the game you like the most? Here are some suggested ideas, pick a top 3 of these that you feel represents what you like the most:
Casual play-mode
Tournament/Competitive play
Squad Building
Repainting models
Customizing new scenarios or campaigns
Creating new ship stats
Creating new models, scratch-built or "kit-bashing"
Coming up with ways to "improve" stats of ships or upgrades
Having great pre-painted models
Feel free to add other ideas.
For me:
Casual play
Creating new models
Having great pre-painted models
I have painted hundreds of models but it is nice to be able to pick up and play with a new ship without having to assemble, research and paint. Still it is nice to have some input in the models to show that they "belong to you". The pick-up and casual play of the game is great for introducing to new players. Trying random squad builds is fun too.
