I've been watching and reading a bunch of discussion on the game, and combining it with my own playthrough have come up with some interesting notes on the game.

1: This is an asymmetric multiplayer game that while acknowledged by a majority of the playerbase, the full concept of which is not grasped by everyone. A well done very asymmetric game makes two almost separate games into one. In this case, the hunters and the monster. They all abide by a few shared rules but each play differently. The different playstyles can be called separate games entirely depending on the players personality. For example, some players will play anything in Evolve. Others only want to play as Hunters, and then only as a set few of the Hunters. Still there are some players that only want to play Monster. These preferences are so strong for some that they will leave the lobby if they get assigned a role they don't want to play. Then some hunter get upset because either they wanted to be monster and now that the role is actually open but they can't swap to it, or now they won't have a challenge hunting a bot monster. Also there seems to be a "You must play as the monster timer/count." in the matchmaking. You can play with a pug and everyone has the role they want, but eventually you all will get shaken up into other roles. Grouping with 4 friends or less is suppose to always make a pug the monster. This isn't always the case either.

2: The game should have been advertised differently. MANY people thought it had Day One DLC (finished gameplay content sold separately at release.) The only extra content out right now are skins for the monsters and weapons (the pics above.)

3: It's worth it's price now if you enjoy it as it is now. I knew from my time in the alphas and betas that I greatly enjoyed this game as a whole, and preordered it then. If you are unsure, I would highly suggest you keep a look out for it going on sale as you may get more bang fore your buck and get more content you feel it may need.

4: Points 2 and 3 above lead to a potentially really big problem. The game's community is relatively small (I've actually run into some people multiple times in matchmaking.) and doesn't look like it will change anytime soon. People will inevitably drop off as time goes by. Only the die hard veterans will remain. Enter the Steam Summer Sale for example. Sudden wave of new players who will likely get grouped with the veterans. This has 3 main outcomes: The veteran community shows no mercy and no manners, turning away the new players and potentially wasting their purchase. The veteran players are welcoming and understanding and show the new players the ropes. The new players will still likely get their asses handed to them but it wont' be an outright miserable experience entirely. Or neither happens in mass and people come to their own conclusions on their own or with outside help.

It will most likely be a majority of the third option with the rest being the other two options with one of those two options dominating the other. Hopefully it's just the latter two so the game grows, making it more fun for everyone.
Personally I'll try to be the second option and be as welcoming and friendly as I can be. I normally try to be anyways.

5: The price for the 4th monster is $15 USD. With my new understanding of the game and it's development, I still find it hard to justify $15 for it. $10 I feel would be a worthy estimate personally. $15 I can understand for all 4 of the next hunters. An option to buy them individually for a reduced price each but more total would be nice though. Keep in mind though that their pricing has not been announced. Nice thing about this dlc is that you don't need to buy the content in order to play with or against them. So everyone's game is enhanced to a degree by the few who do purchase these.

6: The other game modes add some nice diversity. There are many different strategies both sides can use on each mode. Hunt could use some of that though. It does have it's own nuanced strategies both sides can use, but some other mini-objectives in hunt could add some diversity to the main mode. For example it's been suggested that should a hunter(s) be killed by the monster but other(s) remain, that they have another option to work at should continuing the fight be unfavorable, which it regularly is should that point be reached. Currently, the hunters just run and hide as the game is flipped to the hunters being hunted. If certain characters were chosen, the hunters can choose to make a great trap now that the monster may be coming for them, if they have those characters on the team and they are alive. The monster can choose to find the remaining hunters and kill them, or continue hunting wildlife and level up, potentially nullifying that great trap factor.

This is only really a concern when pugging through the skirmish option. As Evacuation adds other objectives/bonuses based on gameplay and custom matches can have these bonuses manually chosen.

Result of all this analysis: Optimal way to have the most fun in the game is to play with 5 friends in Evacuation or Custom Games since everyone gets to play what they want to play, and many factors are added to the gameplay. Pugs have the typical pug problems, but the main issue for pugs comes from the asymmetry and matchmaking itself. Is the content worth it? Depends on your own personality and preferences. Be a savvy shopper and find out.

Anyway, should you get this game, I'll gladly play with you should you purchase this now or in the future. Hit me up on here or in steam and we'll have some fun hunting.
