Lastly, the multiplayer ladder service (similar to the OGL ladder) present in the Korean version is reluctantly absent here because of the lack of stability on the code of the ladder. Dave Nixon comments, “Because Jamie's ladder system is in it's early stages and cannot support very many users yet, we opted to remove this option from the RealNetworks version until that could be improved. We can update to include it later once the system is robust enough to handle higher volumes." So that's good news.
Other than that however, the Korean version and the RealArcade release are pretty much identical! We've got you covered on the music and movies bit so all that you're missing here is the ladder service, which will be available to North American players sometime in the future. Maps that were added in the 1.03 patch for the Korean version have also been included in the RealArcade release.
Player models are quite intricate and extremely well designed. Each piece of equipment that you suit up with makes a large visual alteration to your robot. Weapons are also well designed in that being unique, conveying to your opponent just what muzzle flash he will see just before he dies. Melee combat is present in the game, but you can tell that the game wasn't designed for it - melee weapons are fun to play with (if you can get close enough to your opponent) but they certainly aren't my choice weapon in Axis.
Level design is very close to that of Q3: A, but not limiting the player to 4 axis (pun not intended) of movement and giving them a lot more open space; with the exception of certain maps where close combat is what it was designed for.
Gameplay is a ton of fun and very well balanced... with the exception of one weapon - the SR-7 Sniper Rifle. This one-to-two shot kill weapon is regarded by some as being just too powerful. Sniper rifles in a lot of games usually have some balancer - in Tribes it's energy, in other games, it's limited ammunition or reload time. However in Axis, the SR-7 is not limited [heavily] by ammunition, energy, or a considerable delay in reloading. However, depending on the server you play on there is a certain unspoken rule about using SR-7's religiously. Some players respect that, others don't... it's all in the server you join and the people you play with.
Some would argue that the net code in the game is pretty bad but personally, I haven't found it to be bad at all, so this is something that I'll leave open for you to decide. The game uses a client-to-client internet mode versus the more popular client-to-server mode. The use of this mode is what cut out the dedicated server option in the game, which is a real let down. So, whenever you want to play or host a game you actually have to have the game up and running to do so, bleh.
Nevertheless, you can't get over the fact of how fun this game is to play. I'm an anime nut, so naturally the artwork and overall feel of the game truly attracts me. However, it isn't overdone so those of you who don't care for this style of artwork won't get sick of it. There's just something about kicking the crap out of giant robots that's oh so fun.
* Roughly translates into 'One kickass game!' in Japanese. It literally translates to 'game kicks anus', but I couldn't find a direct equivalent to 'kickass'. Yes, I know the game is Korean, but I only know Japanese
