as others have said the fact that you need to cough up cash for additional commanders, the blizzard system is pants, etc...
Nope, its been changed. You can get commanders from just playing the game as random drops now.
but most importantly CoH1 supports mods. CoH2 doesn't. there are tons of CoH mods which make CoH even better than relic's original design: Blitzkrieg, Eastern Front, Modern Combat, Joint Operations, Europe Theatre of War etc...
I still play Blitzkrieg mod which is awesome.
Mod support is coming in a future patch.
Right i miss this game so much, i played like 7.2 million hours on the original and I have actually started to harm myself because ive not got this version.
So.... please can I ask the following:
1 - What makes the original better? I mean surely the gameplay is the same?
Better graphics, little things like being able to vault over walls, more variety in the game due to many commander choices, instead of just 3. Also has difference resource / capping system. Imo a better Veterancy system as well. I used to think Coh1 was better, but after playing Coh2 for awhile, coh1 doesn't seem as good as it used to be.
2 - Will i get online games easy, the original was easy to get games... always circa 5-10k players on
Games are pretty easy to get in automatch, especially since WFA was released. They have also added custom lobby's to the game so its easy enough.
3 - Can you do online 4 player v 4 AI coop?
Yes you can
4 - What DLCs to get? All of them?
So basically I can get the COH2 key for £8.99
Then the Southern Fronts Mission Pack for £1.49
Victory at Stalingard mission pack for 3.49
Case blue mission pack 3.49
Not sure what they do, but i might as well add them
Depends on what you want to do. The Theatre of War stuff are mostly single player missions / scenarios, some of them are CO-OP but can be played with the AI. I enjoyed playing them but it depends if you like Singleplayer or not. You can buy commanders for use in Multiplayer if you want, some of them are good some of them not so good. You can actually unlock them now from playing the game, you have a chance to get random drops at the end of each match.
Then there is this new western front thing for 13.99
That is the standalone expansion that was just released. They have added USA as well as a 2nd German faction.
If your expecting a clone of COH1 then you may be disappointed. The game is pretty similar but there are differences but I think it is better. I've racked up almost 600 hours of the game now, as well as playing the Alpha, Beta and then WFA Alpha. The game has had quite a few changes since it was released and its much better now than it was.
even if they actually do Mod support eventually, I am afraid that making good mods take a long time to make, and with little interest in the game it may be too little too late.
