KylieDog, you must forgive me. I usually am not taken aback. It's just that your post was filled with a large number of ignorant, and also surprisingly inept assumptions that simply aren't, nor could possibly ever be true. I will lay them out for you now:
1. PC/360 games are exclusive Xbox 360 games - Not only was this assumption contradictory, but it is also generally accepted as spin. If you mean to say the PC doesn't count as a gaming device, then you're simply wrong.
2. Exclusive games are always over-rated - This is easily disprovable. Look at Lair, or Haze. Those games are possibly even under-rated, yet they remain exclusives. Too Human is another good example. According to you, Fable 2, LPB, Uncharted, MGS4, and Gears of War are all over-rated, because they are exclusive games, and reviewers, knowing this, over-rated the games, and users, knowing this, overhyped the games. The latter holds a ring of truth, the former is absurd. Too bad this wasn't your only ignorant assumption, or you would be fine.
3. Game reviews mean nothing whatsoever - This is probably your only assumption that you could find anyone to agree with you on. I do agree that review numbers mean very little. Radiant Dawn is one of my favorite games this gen, in fact. Yet, reviews obviously do mean something. They keep people, like myself, from buying games that are rated very low, and peak my interest in games that are rated very high. They are also the only quantifiable way we have of determining a games quality.
4. Bioshock is a bad game - This, of course is an unprovable opinion, but it becomes an assumption, if you've never actually played the game: While most critics agree that this game is a masterpiece, a few users have claimed that it is a tad over-rated. None have ever said it was "bad" as far as I recall. You've implied this, harshly. Again, you've never said you've actually played it, and I contend that you haven't. My reasoning is that no one who is able to create a VGChartz account is ignorant enough to play through Bioshock completely and claim that it is completely bad. You will either concede that it is not, or I have no choice but to maintain that it is a faulty assumption.
5. Bioshock is an Xbox 360 exclusive - Again, Bioshock is not, nor has ever been an Xbox 360 exclusive. It is also on the PC, and always has been. The PC is a very competitive gaming medium, and even if you did consider this a 360 exclusive, reviewers, and everyone else on this forum, does not, effectively disproving your "Bioshock was over-rated because it was an exclusive" argument. This is even more true when you realize that the PC version has its own review score on gamerankings and metacritic, also averaging a 96/100.
6. Left 4 Dead is an Xbox 360 exclusive game - Well, the games lead development platform is the PC. The Xbox 360 version is a port. The last time I checked, the PC was a competitor for people deciding on which platform to purchase the game, and it'll also potentially sell more on the PC via untrackable DLC, taking sales away from the Xbox 360. This game is more of a PC exclusive game than an Xbox 360 exclusive game, if anything. In truth, it's a multiplat. This also contradicts your measuring stick of sales as the only way to determine quality, since the game will sell well, but you would only count the sales on one platform. You would also claim that this game will defaultly be over-rated and over-hyped, because it appears on the Xbox 360, and not the Playstation 3, which is actually probably very insulting to PC owners as well as 360 owners looking forward to this game.
7. A games quality is always determined by sales - You've said more than once that Bioshock is showing "its true colors." Since you are obviously speaking of the game's quality being sub-par, and since the reviews have all been ravingly positive, I assume you're speaking about its sales on the PS3 showing the true color of the game, as being bad. By inference, you believe that bad sales equal a bad game. I would disagree. Okami, Beyond Good and Evil, and Zack and Wiki would also agree, amongst others. According to you, Wii-Sports is the best game of all time. In saying this, you also disagree with everyone on this post, who say the game is selling poorly becasue of time-frame and price, and instead you blame the games quality, which is ignorant.
8. Everything we're discussing is related to Console Wars, and thus PC is an irrelivant medium - That would be an acceptable(though questionable) argument, except it asserts that not just us, but potential purchasers, and reviewers also view all games in the light of "console wars" and the PC is always irrelivant. We're discussing gaming on this forum, not "console wars." You assert that reviewers consciously rate exclusive games differently, with the intent of inciting console wars, since you extend your argument to every facet of the game, including reviews. If you are simply referring to this topic, however, it is sales and gaming related, and we look down upon console wars, and fanboys on this forum, and we respect the PC as a powerful gaming medium.
Now, KylieDog, I hope you have seen how ignorant your assumptions are, and how none of your arguments hold any water. If not, I would be glad to explain further why you don't know what you're talking about.
