deamento: So I just played xcom enemy unknown and I wondered, are the originals good as well? I know they're not on GOG but still... and if they're any good, should i buy the complete pack or only one of them?
The first one is still a "different enough" game to warrant another playthrough. But it is old and it shows. Not talking about the graphics, they are still great (imo). But a lot of interface improvements have been made in the past 15 years which you will miss in the original X-Com.
Xenonauts will be released in a few weeks, which is probably cery close to the original with more modern features.
Considering you can get the original for just about nothing, I would at least try it.
And I must say that Apocalypse is the best out there. The complexity is stunning. Very underrated. People didn't like it back then because it was "to modern" and made "to many changes". Yeah, that mentality hurt gaming already back then.
