So... we've known for a while that #266 Breaching the Great Fourth Wall of @@NAME@@ was inspired by the XKCD map of the internet (the last option explicitly references an "XKCD survey map"), but I somehow managed to miss before that NationStates is actually on that map (it's on the southeastern end of the MMO Isle, next to the Gulf of Lag). With this in mind, we can make more sense of the nations it references.
1. "Stalclaft" is a reference to Starcraft II, found a short distance to the west of (but not immediately bordering) NationStates. The "particular gaseous resource that could prove profitable for us" is a reference to vespene gas, a fictional resource from the game that's so famous it ended up naming the trope. The fact "the place is a war zone" should hopefully be obvious.
2. "Cea-Dicee" is a reference to CDC Games, found on the map as a large island separated from NationStates only by a very narrow channel. It's a company mainly running several Chinese MMORPGs that, despite the island's size, seem to be fairly obscure in the English-speaking world. However, the presence of EVE Online on the island is a clue. According to Wikipedia, EVE Online isn't actually from CDC Games, but had a licensing agreement with CDC games until 2011 - and the map is from 2010. So that's what's being referenced. EVE Online is a fairly well-known space simulator, so that explains the "what little we do know about them implies that they have SPACESHIPS". (Interesting to note is that spaceships weren't brought up with Starcraft II. While the game takes place in a science fiction setting, the gameplay focusses on land battles rather than space ones, with spaceships appearing more in story cutscenes or as maps than as units you control in gameplay.)
3. "Subspais" is probably a reference to SubSpace, a space-based shooter. It is unclear to me why the XKCD map depicts it as underwater, though it may have to do with the fact that, according to Wikipedia, the company owning it collapsed, and "independent user-run servers became the only choice for hosting zones". Combined with being one of the earlist MMO-like games, the notion of it being "ancient ruins" holding a treasure trove of historical knowledge (and more applicable science, since it's still a science-fiction setting) feels apt.
4. "Uoeq" is actually an island on the map containing two separate territories, the larger UO (probably Ultima Online) on the west and the smaller EQ (probably EverQuest) on the east. There's a mistake in the issue (as last reported): it claims Uoeq to be to the west, whereas this island is in fact to the east of NationStates on the map. "Sekonlif" is of course Second Life, placed on the other side of the Gulf of Lag from NationStates. None of these three games are referenced beyond their names, instead being treated as generic victims.
