I'm with you on that for sure...So yea, nothing innovative about Redfall. It took me 5 seconds to see that it's nothing special and something I knew I wasn't playing at launch (or ever for that matter).
It's really like trying to make a hit record. I write dance music and each time I try to think of what can be different about what I'm writing that hasn't been done before? It's why I give Kudos to Kojima for Death Stranding because while it wasn't 100% received with open arms by everyone, he did something different, to which I haven't really played before (at least for me).
I don't know if we'll ever see a constant stream of innovative ideas with each release. So as long as developers are doing their due diligence with the story telling, mechanics, etc. and making sure that those bits are executed collectively, then they should have a decent launch and favorable reviews thereafter. That should be the bare minimum for any game quite honestly.
What I struggle to understand sometimes is, what is happening behind the scenes to where a game is delayed with a new date, only for that to not help in the final retail build of a title? Delaying is fine, but don't provide a release date until x, y and z are spot on. Are investors really saying they don't give a fuck and say push the game out right now despite it being broken? I want to know what's happening there. Maybe the budget to pay Employees gets exhausted well before release? It's happening too often across multiple studios, so it's interesting to me.
Coming up with something unique or 'game' changing isn't easy at all, which is why most people keep doing the same thing. And most won't take the risk specifically because their budget, investors, resources etc. simply don't allow it.
