We may be missing something though about the fact that this one is made by Infinity Ward so returning maps are likely to come from only their assets than the others. Its why Dome is back and I would expect Rust to come in eventually as James mentioned before as they did create it. I wouldn't know if maps have crossed over between developers but I wouldn't expect much have, if ever.
Whether we like it or not, the Developers are asked by Activision to churn out a new game every couple of years which means they dedicate a large portion of that time to the Campaign and re-use old assets where possible. If you don't re-use assets its widely known brand new games take around 7 years to create, especially AAA games. So within a few years they focus efforts on what Activision want. Yep, old maps after a while are annoying if thats all you get but thats where I'd expect a new map every so often to balance out the map pool.
I don't see that from FGers and most other places I read about CoD. Damned if you do, damned if you don't situation.
I want to be clear I don't like whats happened to most CoDs and the model that Activision have been following for years. What we all agree here I can largely see is that CoD needs a culture shift under the hood to a different type of Multiplayer development pattern, maybe one that matches the likes of Overwatch.
But what we can do is also realise that this isn't where they are now, so I'm looking at this game on its on merit on how fun the gameplay is and how much content we have to play on it. Season 2 looks okay. Not bad, but not super great either. I think sometimes we'd all do ourselves some favours if we could open our minds to how it feels on both sides rather than just saying a game is crap 'just cos'. I see the same thoughts in how Destiny was over the years and it turned out stronger. Not sure this franchise will go the same way, but for right here right now, there is no surprise to me why so many FGers are enjoying a CoD game for once, and maps not being new won't change that feeling a massive amount.
Maybe by Season 3 though it will as burnout starts to hit if the game goes too long without enough variety in the game. Meaning New and Returning content btw 🙂
