I made an account to chip in here too.
Sadly i think difficulty is an issue: people want to experience VR of different skill levels, and Battlezone has generated interest from my circle of friends because it's a "proper" game.
First up the price has put off a lot of people, they may like the demo, but £50 is a lot of money for some (having just spent up to £500 on all the VR gear required) to take a punt on.
Then there is the difficulty, and if they get destroyed 3, 4, 5 times in succession on Easy some may not keep going. As Enuebis said there's a culture of trading into CEX etc to recover losses on a "bad game". They may lack pushing through the barriers to learn and adapt.
It does seem to me the difficulty is too flat. If you take other co-op games, say Earth Defence Force or Mass Effect 3 multiplayer, there is a world of difference between a team playing ME3MP on bronze or soloing platinum. Both are possible with skill and equipment, and suit different people.
With Battlezone the difficulty starts tricky and ramps up, you need to hook people before you punish them. e.g.: if playing solo, the gank waves of enemies feel harsh if you have the "stop the upload" mission, or the hack with both bases. I accept these as lost missions, as just try to earn as many credits as possible, while not losing a life.
Don't get me wrong i'm not adverse to hard games, i enjoy genres with games like Demons/Dark Souls, Operation Flashpoint, or Ghost 'n Goblins, but i have to ponder if the decisions made are best for a launch game on essentially a new platform.
Like why have shared lives, but not shared credits? I see people furiously boosting to scoop up orbs before other players, often putting themselves or the team at risk. If credits were shared, so no matter who scooped them you got shares on mission completion, it may adjust "greedy" gameplay.
Likewise sharing lives means players joining and essentially making progress harder by dying and using up all the saved lives. If lives were individual, or unable to be used until you had completed at least one mission, it may resolve things that side. It just feels odd you have part-sharing mechanics, and part greedy: go all out on sharing say.
Another thing which may ease things would be like introducing "shield gating", whereby if you have any shields left, the next shot does not bleed damage through, but expends all energy for that shot. This would stop being one-shot, and give players a chance to respond, and make light tanks a little easier to use (being one-shot killed with max upgraded and full shields on that sector feels harsh).
I enjoy Battlezone, but just wish it was more accepting to new players, and adjusting difficulty on Easy would help a lot. I just hope something is done soon before the hype wears off, and it becomes associated with a game to avoid buying.
