I don't know why you're so upset OP. Most of the time when people bring up other games it's for comparison between this game or that game. The majority of the time it isn't "ZOG you guys should play "X" game over FFXIV, it's the bomb!" I don't think I've seen one topic saying how great the new WoW expansion is.
Now what I do see a lot of is people comparing certain aspects of the MMO genera against each other. I.E. WoW is successful at Y and X. Why can't FFXIV emulate that, or at least build off of that? Or FFXI did such and such this way and was one of the better parts of the game. Why wouldn't SE incorporate that same system into the game?
Games are always compared to other games. All FPS are going to be compared to either Halo or CoD. Nothing you can do about it. And to say don't compare this new FPS to CoD or Halo because it's not that game is stupid. The goal of a company is to make a better, or niche, product that is currently out. I.E SE makes video games, mostly RPG, so they want to make the best games in that genera, or create a niche game i.e Final Fantasy Tactics and pre-WoW FFXI. In this example, being FFXIV, it is a MMO released in a market that is currently saturated and has many niche markets already. FFXIV can not and will never be able to compete with WoW. Which really sucks, I thought it could have been the game that made blizzard lose sleep at night. So it's not going to be the best game on the market, now it's going to be a niche game...but for who? Causal gamers won't play this game, it's not causal friendly. Hard Core raiders won't play this game their is no raid/instance/HNM/Kings/???? content yet. Action RPG players won't play this game because all the battle system is is 1,1,1,1,1,1,1,WS,1,1,1. I'm sure I could continue going on and on.
So when people complain about a certain aspect of this game and compare it to another game out there that did it successfully it's because those people want to play this game for that reason. I.E people who complain about the class system not being defined enough, or not flexible enough via the stat allocation system wanted something like the FFXI class system, just better more customizable, what we got was the current system that can't decide what it wants to be. Most people complain about the lack of quests and refer to FFXI or even WoW as a game that did quests right. It's because those games incorporated all the NPCs in the world. Not just stuck people here or there that ment nothing to the player at all.
When I'm looking for a good FF MMO i'm going to compare the game to XI, simply because that was a successful FF MMO. I would hope that SE took what worked best from XI and would incorporate that into FFXIV. Instead it seems what they did was the exact opposite. They took what worked and was great about XI and either dumped it or did the complete opposite, case in point the AH. This game will be compared to every other MMO that is out there and will come. As will DCUniverse and the new Star Wars when it comes out. Same as any action RPG will be compared to ME2, or any hack and slash will be compared to GoW.
