Reminds me of when
America's Army in 04 July 2002 started out as a recruiting tool to show civilians of a virtual soldier experience.
As you can see, the game changed drastically from version 2.8 to 3.0, and was basically a different game with a completely different gaming engine. I stopped playing it after version 2.5 since it no longer supported other operating systems. From version 1.0 to 2.5 all operating systems were supported, and played great on them. There was even talk of how there was better framerates for the non Windows versions; Linux, Mac, and BSD. Soon afterwards it became only Windows based.
Yes, it does suck when a version becomes a completely different game; it is progress. Deal with it, or stay at the same version. If you do not move forward, you will be left behind. I left America's Army because it left me behind, but I still enjoyed it. It is the game that was the most realistic to me as for fps gaming is concerned, however I have been playing Arctic Combat which reminds me of what America's Army was like when I left it. I am sure that the military has expanded America's Army further than anything on the market, and for free. You will get to go through basic training, some combat lifesavers course, escape and evasion, and other military training. It is of course a very simplistic condensed version. An example is the combat lifesaver course; A forty hour course you can complete in fifteen minutes in the game. It only gives you a taste of how the military trains and how to work as a team. I am not trying to advertise the game, but I would suggest anyone that likes FPS games to download it and check it out; it is free.
Well I slightly went off topic, but was trying to get my point across of games change, and one would just need to go with the flow, or be left behind. It is not a threat, but just a fact that everything changes, and we must all move forward.
