Yes i did a lot.
The Gameplay was the best in a WC Game, in it Missles made finally sense. In WC 3 and 4 i basicly never used them unless i basicly was right up the Enemies butt, a few inches further and they basicly always evaded. (btw that part makes WC Saga better) The Fighters were nice and you could feel the huge technoligy diffrence compared to the WC 3/4 Ships. The Dog Fights were in my mind even more intense than in WC 3 and 4.
While i kinda disliked the main character actor, mostly i guess because i wanted to continue as Blair. In the End i got used to him. What i disliked was that despite this huge ship, you hardly had places to go and it was much more straight in the story line than the games before. I hardly felt that i could choose something. So for example i missed that you could choose on which female character you go flirt on and start a romance with.
I also liked the story as it was interresting with all this phropecy stuff and the intro sequence and in general it doesnt seem to be that bad, afterall the same story arc was used in the Star Trek univers with Voyager and Species 8472. I remember seeing the Voyager Episode on TV and when they blowed up the Borg Planet i was like "thats soooooo Wing Commander rip off".
An honestly after all that time and all that happened, to make another game with the Kilrathi as the main evil force would have been ridicelus. After such events if story writer go with that story plot than it only shows that they cant think of something new anymore. They only thing i disliked in the story is what they made out of the Kilrathi, that proud honorfull race became a huge peacefull hippie party, they could have given them some worthy backbone and let them really join the fight, so they would have stayed true to some of their believes.
Oh and the only odd thing in this game was, well while it was a lot of fun, you have here a race thats supposed to be more evil and stronger than the Kilrathi, you never had faced their technoligy before and then i get a shot down count from over 10000 kills. Why should i fear an enemy that has such lousy pilots?
Oh and the really only huge problem i have with WC 5 is the end.
[spoiler:2ykt7fr3]I mean there dies (yeah i know that we dont know what happened with Blair and that he may had returned, but from the Confederation point of view he is KIA) the BIGGEST war hero of the Kilrathi War, the Hero that stopped the war with the Border Worlds, the designer and think tank behind the Midway, the main character of 4 WC Games and yet there is absolute NO memoral ceremony for him in the End. Just a stupid "he didnt make it" line.[/spoiler:2ykt7fr3]
