I am one of the people who regret not getting it earilier. I started with CoD and kept playing it until MW2. During this time I played some CS:S and loved Raven Shield. Even played in a clan for 3 years for these two games.
So the middle 'phase' was just some CoD4 and MW2 for a year or two. I just got k/d ratio's of 3 on average (slightly exaggerated) so changed to pistol owning the crap out of people to reduce that to 1.5.
Since that wasn't as fun in MW2 and MW2 had some other problems, I was glad BC2 came along. It had some more fun team elements and wasn't as easy as CoD.
However than BC2 decided to kick me everytime I played in a server for 10 minutes, since that wasn't fixed after half a year, I also decided to not buy the next Battlefield.
So then Blobs came out... I was actually quite disgusted by the game, paying 60 euros for some new weapons and maps was just too much. (edit: the free weekend confirmed my feelings
)
[Dec 2010] So when looking at the Blops forum, I suddenly noticed a weird topic:
[paraphrased]"Don't buy this game, wait for this one!".
In this topic there was a link to a fun trailer with some russians getting blown to bits in a very nice manner. I was sold on the spot and I went to the Tripwire forum. Too bad the game wasn't out yet, so I decided to buy RO1 in the meantime.
I really hated myself for never noticing Red Orchestra before. Although I hate the pixel hunting (shot half a pixel yesterday, and it wasn't even 200 meters) I loved all the rest and played it ever since.
Inconclusion, I have always been a CoD player until blops killed it for good. So I am the perfect example of a CoD player turning to the RO franchise. RO1 saved the day and RO2 will save tomorrow:IS2:
