Oh hell in that case let's just label everything with guns and action soulless COD clones.
And immersion is subjective. I've been just as immersed in these titles as I have been in any of the others. I like these new titles more in certain aspects.
The DLC is a one shot. And besides, it's only a few hours long to complete. It's more of a fan service than anything.And they did go back to their roots with the RE5 DLC, which was very well received. Not to mention the upcoming 3DS game... so it can be successful, they're just choosing not to.
We - the fans - know that going back to the roots could be fruitful, but Capcom (unfortunately) doesn't believe so. Who knows, maybe in a few years if the series is still alive and kicking ... but for now, their focus will primarily be in TPS style action.
