//but I've read more than my fair share of times "stay way from X and pick up Y instead." Well you know what, I've already picked up Y, played the hell out of it and looking for something else now.
>>If y is a much better game than x i'd like to know that. That can be an indication if you will like x. If a reviewer thinks that half life 2 had a better single player experiance than doom 3 and can back that up they should mention it. To people who played half life 2 they have that yard stick, to people who haven't they will go read that reviewers half life 2 review.
Games in a series especially should be compared. regardless of any two month time frame. Many people wanting a review of GT4 or Halo 2 want to know what changed or improved since the last game. The review has to serve new players as well but old ones can't be left out. I think it would make a strong review to compare the multiplayer of one game to it's predicessor or a close competitor in the genre. If doom 3's multiplayer was a dropped ball compared to quake 3 that must go into the review.
For the proffessional reviewer problem, reviews should be gone back to later and properly finished or updated. The whole multiplay experiance should be properly reviewed after release and added. If multiplayer changes later within a relevant timeframe(based on popularity, or sales, or anything else justifable) that should be added as well. A review of MGO would be different today than it would be during the first seven days where everyone was a noobie. When BF2 gets a patch that adds something like no_vehicles option that should be attached to the bottom of the review. People do read legacy reviews sometimes and it would be nice of they were indicative of how the product ended up. If a game becomes less playable because of low playercounts or rampant cheating that would add to a fair review.
Niching or fandom could do to be mentioned as well. Someone who likes realistic racing sims will like one much more than someone who just likes arcade driving. To use a /10 scale for effect only here, a 10/10 F1 game is a 4/10 to someone who just likes need for speed, How should this game be reviewed? Perfect? crap? the middle between perfect and crap? Can it be given the perfect must buy praise if only some fans will feel that way? Should it be treated down because it is only perfect to some people? Currently we are stuck with scores so this needs delt with.
Buy/Not buy could be great if it included many frames of reference. The mag or site can have it's main universal score but then give advice to the very specific fan types seperately for your real score or buy/not buy
