That is how business works. Big companies buy small companies. Some of the games they make/produce a very good.
I can't understand how people hate EA because their games are "rushed" when they all flock to Valve. Valve games look rushed even if they take years and years to make. Nearly every Valve game I have seen looks like it was made 5 years before the time when it was released. And before you guys go wah wah graphics don't make games, the most important thing to do when trying to make anything look like it was done with care it to make it look nice. Basically, Valve is a company that is loved because instead of being efficient and shiny, they take 5 years to spew out their bad-looking games. EA may be an "evil corporation", but they can keep things on a decent timeline and make them look nice.
Graphics play a part in the game, but emphasis on graphics and gameplay should go hand in hand(balanced). Now for my argument:
The thing is that most Valve are good. Look at TF2, during its initial release it was very good and over few years they killed with hats and wierd looking and out of place weapons(some of them balance breaking). Now look at BF3, it hasn't been out for a year and they already have dlcs and a buy everything without working for stuff system.
Valve learns from its mistakes and trys to improve from past expierences, where as EA blames things on pirates and acts like all is fine. Since the episodic system for HL hasn't done what they hoped, Valve said they would bake there titles more so they don't upset fans. EA's fix for everything is a "DLC".
Valve prices things accordingly and drops the price over time as the game gets old and less interesting. EA says that stuff on Steam is expensive and digital distribution should be cheaper. So they go ahead take almost everything off steam, make steam, and make the prices off most of their games around 60 bucks(most of which were origionally 50 on steam).
Both companies take a peak into your privacy. Valve specially says what they scan your computer where as EA says, "we can look for whatever". Even after you unistall Origion you can see strange ips from a DOS Screen.
EA buys companies and then FUBARs them. Look at Westwood, bought out by EA only to have the origional staff fired(expect the guy who played as kane) and replaced by idiots. EA has bought out many companies and has milked many titles by simplifying gameplay. Valve has only bought Turtle Rock studios, although they let them go and Turtle Rock became its on company again.
Now for mods. Mods are something that PC games will always be something console games won't have. If a mod group makes something interesting Valve will hire them for their talent to make a game. EA on the other hand will buy out the guys who made a mod and make them create game and also make it unmoddle*cough*BF3*cough*.
