Grabbed Reach at midnight [7 hours ago] but haven't had a chance for a proper sticky beak yet. Mine is still wrapped in plastic but we did unbox a friends copy and have a quick poke around the armoury and forgeworld.
All i've done at this point is fly around in the Falcon - which itself was a lot of fun. Can't wait to jump in as soon as i've got some free time after work.
I'm glad I went and got it at midnight, Now it's here waiting for me and I don't have to muck about during the day.
It certainly does seem to have a classic / 'greatest hits' flavour to it - at least so far...
