Never played a Battlefront game, will never play this one, and I am sure the ones before had a lot more content, think we can all agree on that. Some say that this is the way games are done nowadays, however the thing that I would like to address is that YOU have the power to stop this. Heard rumors about it being an annual series, next year another Battlefront. If YOU want things to change, don't pre-order, don't buy until you are sure the next game did well. If you buy, hate it and tell that to others it doesn't matter anymore, you bought the game already, some game companies only care that you payed and they don't follow the feedback. The fact that you bought the game is what makes them say ''we did our job''.
There is a video made by a good movie reviewer that talked about how he will not buy Battlefront, his name is Jeremy Jahns. If you want more detail about this topic, go watch his video.
Look at Witcher 3, the company knew how to handle extra-content well from what I heard and Witcher 3 HAD a lot of content in the first place, and it won 3 awards this year. A lot of companies should take example, but hey, it's 2015 and people still do this sort of stuff, surely there have been many examples and situations such as this. However, because some of us fought for this, we got a game like Witcher 3.
