Titanfall is a great game, and it has already captivated me for many hours over the weekend. However, there are always areas to improve upon, and it looks like EA and Respawn plan to do this at some point in the future.
EA has already secured rights for a sequel in the Titanfall franchise, which means Respawn Entertainment may be getting ideas for Titanfall 2 already. Titanfall did manage to sell around 700,000 copies in it's first week, but whether or not you'd consider these numbers good for a console exclusive, there's no denying that there was a lot of hype for Titanfall, and that alone should be enough for EA and Respawn Entertainment to consider creating a second Titanfall.
We've already suggested that a second Titanfall would come, and hopefully it will improve upon the few things the current game seems to be missing. This includes more weapon availability, new game modes, and include customizations for weapons and pilot appearance. I think it'd be great to be able to unlock gun camos or other cosmetic gear whilst leveling, and it'd certainly add an extra incentive to keep playing.
EA are also keen on the idea of making Titanfall 2 a multi-platform title. This will mean the next Titanfall game should be available on the PlayStation 4, as well as the PC and the Xbox One.
At this point in time though, i'd say we focus on the first Titanfall and it's upcoming planned DLC. It could be possible that this DLC will include more game modes as well as extra maps and other content.
