All of the below is my personal preference and from what ive seen on the official trem Euro server
1) Instead of joining as Unnamedplayer, I joined as my RL name. Im guessing people are no longer unnamedplayer but C:/users/computername?? Anyways, im not sure what the go is there, but I wouldnt recommend it, as its kind of a breach of privacy (I have nfi if this was just me or 1.2 is programmed that way...)
2) When I minimsed trem the game wouldnt allow me to full screen. This maybe just a beta glitch, but i had to ctrl_alt_del to close it and reopen
3) The game opened at 640x480 (may have been 800x600, but it was very blocky). Some gfx cards on laptops wont support this resolution (akaik) and the game should start by default at least at 800x600
4) The standard GUI from Euro server was very intrusive, I much prefer the standard HUD. Perhaps you could include a HUD menu in options so people dont have to fiddle with settings to try and install a new HUD?
5) Granger spit is weird, it looks like its 'floating' for a split second before it lands. I personally dont like it (but w/e)
Thats about all for now, gameplay wise I cant really judge till I get used to it.
On the plus side I love the option to download from server/website. Alsothe news option is a nice additional which will hopefully get newer players to join the community
