I got it for 45 on a pre-order deal, and do not regret getting it at all. Is it perfect? No. I wish you could at least pick which map you want to play (although that does eliminate the 24/7 map fixation that seems to occur in a lot of games). There is also no dedicated server files offered to use yourself. You have to use their infrastructure, which I do have to say worked fine last night for me.
However the game itself is pure fun. I'm not wanting to sound like I'm aboard the hype train too much, but last night I had the same feeling I had when playing UT and UT2k4 back in the day. It's futuristic, it's fast paced, and the wall running really works nice giving you tons of possibilities for movement when not in a titan. The titans are a lot of fun, and the unlock system seems like it won't be a grind like the BF games can sometimes be.
Even though it has no LAN support, and you don't get your own dedicated server files, I do have to say that the performance has been great. Last night I was pinging 20's all night with no noticeable lag at all. No crashes either, it seems completely stable. Very smooth launch night.
