I don't really remember much of Gears 3's campaign... guess that means it wasn't great. I think I played Judgment with a friend for maybe an hour or two before we got bored. Never tried Titanfall...
Been playing with Forza and there's a few things that bug me about it, as I got deeper in. For one thing, those terrible short city tracks are back; the AI drivers go from being constantly in the way to rear ending me whenever I need to take a sharp corner. Super annoying. Also, the traffic patters (both AI and Drivatar vehicles) seem to switch between:
A. being not much of a problem
and
B. being intentionally placed just to sabotage and **** up my entire world
Still a great game though; there are many ways to cheat the system though. For example, right after I initiated a head-to-head CR boost event I e-brake'd a tight 135 degrees and b-lined it across a random field to get to where the finish point was. Easiest earned 50,000CR ever, race was over in maybe 10 seconds.
Lastly, the map. I really like it but a lot of the areas are a little bland and don't "flow" very nicely, while others feel cramped and tight. I do like the freedom of being able to drive almost anywhere, but the first Horizon's Colorado map was amazing; it just flowed nicely from one region to another.
FH3 is definitely a good game though and I'll keep playing for awhile.
