I have been taking a break from PR, and have found out from help from Arma players here and on other servers how to use addons, and I must say that some addon's in Arma change the entire experience. I recommend getting the desert weapons pack and a sound add on, Chammy's Sound addon is most most excellent (i hear a modified version of it is in fact in use in PR .8).

I have messed around with some Unit add ons and have found that sometimes the more addons you use, or that players use can add to lag on the server, and even to ones computer that doesn't recognize the addons.

Yes switching to and from weapons can be annoying, though i have heard people saying that there is an addon that helps correct that, normally though it would take some time to sling the rifle to the shoulder or drop it and then get a LAT or Javelin or H-AT weapon ready to fire. After watching documentaries and video of soldiers in the field, both recent and from the past, i have seen a lot of the time it does take time, something that modern fps games tend to not put into context.

The TG Arma Server has a mega download of a different array of addons that will hopefully be used on a server that pertains to 2 such maps with different missions etc, and will have an impact within the Arma Community, much like Shack Tactical, SIMHQ, 3rd Infantry, have had with their option or requirement of having to download specific add ons in order to play on their servers.

There is also a RPG called Sahrani Life that puts you as a civilian trying to make a living or as a criminal, or you can be a police officer and try to uphold the law. I recently DL this and its pretty cool (I did participate in the older version until a new version was put out) and though I have had issues on the sahrani life main server due to batteeye client mishaps, I hope to download it again and see what its is like on a full server.

PR is Player V Player and its great to play against humans, but sometimes playing against a well trained AI can be a nice change of pace.
