So you may have noticed I haven't really posted on these forums before but I stumbled across your review in my weekly visit to the site for some ZP action. I really debated whether or not to offer some feedback on your review and decided, after reading some comments and your replies, that you would be open to some constructive criticism. I need to emphasize that I am not trying to 'troll' or start an argument. This advice is so you might try and improve your writing. I enjoyed reading your review and I hope by providing this feedback you will be able to write more and better reviews in the future. Putting aside some clearly misplaced words/typos here is what I have to offer on your piece.
Firstly, as stated above, many of your sentences are too complex, obstuse and unclear. A good writer would be able to recognize a particularly finicky sentence and correct it to provide clarity. An example of such a sentence would be the following:
"This subject matter is very similar to most other first person shooters, but I think that Halo executes them so elegantly such as to allow for a considerably higher depth of possibilities then in others."
A sentence needs to be clear, concise and have proper flow. Perhaps a better sentence would be something like: "Despite its similarities with other first person shooters, I feel Halo's subject matter is executed more elegantly and allows for a game that has more depth than others." While it may not seem as 'intelligent' a sentence it ultimately conveys the same meaning and keeps the sentence concise.
Additionally you tend to add words or phrases to a sentence where they are not needed. An example of this would be the following sentence:
"Naturally there is far more to the pros and cons of each vehicle, but suffice to say, they have all been very well balanced in order to create scenarios where the players have to make interesting choices."
Just leave out the 'suffice to say' part and remove the commas and you'll have a much more direct, authoratative statement. There are several instances where you could do this.
Secondly, do not over-use commas. Commas indicate a pause in a sentence and thus interrupt the flow of a sentence. Not every sentence needs to have one and you've even placed them incorrectly or in sentences where they aren't needed at all. If you'd like an example for the purposes of clarity here's what I mean.
"Like all good sci-fi, the interest of the visuals lies largely in the functions they indicate, and, in a game, actually have."
In this sentence you have four commas. Although there is no strict grammar rule that specifies a limit per sentence, it is reccomended that you really shouldn't go above three for a single sentence. If you are having problems writing a sentence without using lots of commas try reworking it until it flows properly. The above sentence could look something like the following: "The interest of the visuals in all good Sci-Fi lies in the functions they indicate, and in a game, actually have." This sentence has more flow and is clearer.
Thirdly, it was noted in previous posts, your the excessive use of the word 'which'. I used to do this a fair bit as well so I think I can offer a little advice on it. Just leave it out! Watch in this sentence:
"The player also has frequent access to grenades, which are crafted excellently, emphasizing much of the functionality of real grenades, whilst allowing for other strategies which have less in keeping with the modern battlefield."
Leaving out the 'which' results in the following sentence:
"The player also has frequent access to grenades, excellently crafted, emphasizing much of the functionality of real grenades, whilst allowing for other strategies which have less in keeping with the modern battlefield."
Alternatively, and for better flow, you could rearrange the sentence to something like this:
"The player also has frequent access to excellently crafted grenades, emphasizing much of the functionality of real grenades, whilst allowing for other strategies which have less in keeping with the modern battlefield."
Sentences are just a matter of how you work them. Many of your sentences need reworking, not because of the what the content is trying to convey, but because of the method of conveyance itself. In addition to criticisms noted above there are also several review- related issues I would like to point out. You chose to approach your review from the perspective of the positives to be found in the game. I applaud this effort. It is much easier to dismantle something than it is to build it. Too often I find reviews focused on the negative aspects of the game rather than emphasizing what is done well. However, this does not mean one should approach reviewing from a purely positive perspective. Pointing out negative aspects is a critical part of any review on any topic. You seem to have left out some flaws to be found in Halo, unless you are contending that it is flawless, which I doubt.
Lastly, as I recall, gameplay is just one aspect of any game. In future reviews it may be beneficial for you to incorporate some other parts of the game such as the single player campaign, story and the primary characters involved in it. It might also be prudent for me to point out that I am not one of the 'Halo Haterz', who would simply lambast your review regardless of its merit. Halo happens to be one of my favourite game series, I mean my freinds and I grew up playing it. Again my goal here is not to provoke you, but to help with your writing style so that your future reviews are even better. You can choose whether or not to use any of my advice- it is up to you.
Oh and sorry this is so long!!!
