Wow, guess I completely missed this somehow.
It's nice to see that the author of the article got input from both Nick Gollop as well as David Ellis. Too bad Stephen Goss wasn't able to add his insights though. Some good points were brought up in the article, but the discussion made some as well. For instance, people always talk about wanting a spiritual
successor to X-COM, but even if that would happen they still might not be happy as the game would have to recreate the emotional involvement. Therefore, any remake would have to be an emotional
successor as well. That could be tough.
Can a "true" X-COM successor ever be made? Sure. Can it be done by an independent group with no ties to the original game? Sad to say, probably not. What we need is Julian and Nick Gollop back at the helm along with David Ellis. Give them complete control over every aspect. And for christ sakes, let them complete the darned thing. Don't cancel it.
The one thing you cannot do is satisfy proponents of both Real-Time and Turn-Based combat. This was attempted in Apocalypse and didn't quite live up to expectations. Sorry to say it has to be one or the other. Besides, if you spread yourself thin by splitting efforts between the two combat types, neither will be completely polished. By focusing on just one, you can perfect it and reduce the bugginess.
Fan involvement is also a necessary part. You need the insights of the fans to provide suggestions and to play-test the betas to catch errors. A big issue is also the game specifications. If it can only run on the latest and greatest computers, only those with a system powerful enough can play it. It is completely possible to create a game that isn't taxing to both video cards and processors while still utilizing better graphics.
