Re: Medieval 2 Gold Edition questions
It really depends on how you are going to use the game. There is a patch 1.5 (or1.05 depending on notation) to kingdoms.
If you use the Retrofit Mod, this takes the Kingdoms exe code to play (I play the campaign game) in M2TW. This means no additional patching is needed. The Retrofit Mod is really an unofficial "final" patch to M2TW. No other patches are then needed.
Sparty's suggestion is also perfectly good for an approach.
btw, why do some of the units stand still when I order them to attack? or are there still bugs in the updated game?
If you are commanding each unit individually, the do not move if the way is blocked (too many units in too small a space). Some units take a bit longer to visably be moving such as cav which is slower to respond.
I think that the code is not going to see another update. M2TW and Kingdoms are complete as far as the designers are concerned. The effort is now on the next game. The code has a great deal of open access for you to modify if you are so inclined.
Also check out the hosted modifications sections for more information. There is something for everyone there. I am still playing the Campaign game (now using the Retrofit Mod) and quite happy.
