Graphics are an 8/10 only because the graphics are still same and are still great looking and can merge you into the game. The games still remain in the same which I think is a good thing, it keeps the game original. But looking at the games it shows how much games have change over the years from 1995's Arena and seeing what Skyrim looks like it shows how far video games have come.

Sound is 10/10 the soundtrack is great and as remain unchanged which I think is a good thing and the amazing soundtrack from Morrowind is still as good as it was back in 2002 and it still makes me want to go on top of a mountain and feel powerful. But  the voice acting in Oblivion is still as bad and funny as it always was which always make me laugh when they stood straight and never broke eye contact.
 
Addictivenessss is only a 6/10 as the games dose get very boring and dull after you finished all 5 games as you normally do same thing in the first game. Which is go to the castle get this part of the staff, then go to another castle and get another bit of the staff. So game can get boring after while.

Story is 5/10 as the games story remain the same as they where from day 1 so if you want the full story, I would look at the individual game reviews, but here a basic ones.

Arena Emperor Uriel Septim VII has been imprisoned in another dimension by the Imperial Battlemage Jagar and you must obtain various artifices from all over Tamriel to bring back the Emperor.

Daggerfall you are sent to Daggerfall in High Rock at the request of the Emperor. He wants you to do 2 things. First you must free the ghost of
the dead King Lysandus from his shackles. Then the player
must discover what happened to a letter from the Emperor to a spy that works for him.

Morrowind: The Morrowind
government, already weakened in power over questions of authority, is
further threatened by the re-awakening of the ancient curse and you need the save the province from the evil god

oblivion : The emperor is killed, and you need to give the Amulet Of Kings to his only son that still alive Martin Septim where you need save Tamriel from the Mehrunes Dagon from the oblivion Crisis

Skyrim: Your the last of the dargonborn and you must save the world from Aludin.

Depth is an 8 all the games are big, very big there a lot to do and many places to find and many side quests you can't run of things to do for a long time. It will take a long time to finished the games 100%. There so much lore within the games as well within the books. I've never seen so much lore in a game that wasn't made by Bethesda.

Difficulty is an 8/10 that only has the first 3 can be very hard as sometimes your attacks don't hit what you want and there is no quest markers. But Oblivion and Skyrim are okay but get harder with the dragons as you level up. 

This is a decent first review but it could use some improvement.

- Your already have good structure by separating the different categories but could use a little more detail. Also (and I apologize if English is not your first language) you need to make clearer sentences.
- Your story paragraph is pretty confusing. It this game several stories put together or is it divided in several chapters?
- I love it when reviews compare the game with others games (when it's possible) so readers know what it's about.

janus : Thanks for the comment. I know my sentence sometimes don't look clear I have dyslexia so it hard for me and its 5 different games in one collection Too answer your question about the stories or several chapters question.  

I will take your comments about my sentences to help me make my reviews better in the near future.

I have Skyrim and i love some pieces from both skyrim and oblivion but I never played the rest. Doing the story for each game is a good plus and I like the way that you format everything. The only thing I can think to make it better would be to make it just a bit longer, especially if most of the review is concentrated around the story, but other than that this is a great review.
