I had a post yesterday asking why use open play, and it turns out the only reason is to gank or be ganked.
But the fact you can advance in the game running solo only, imho, really makes the game lose something.
A lot of the fun of Eve is the fact that the risk is always there, and the level of risk is reflected in the level of reward.
But in ED, you can go do everything with no risk. (Interdiction by NPC's isn't a risk, its easy to avoid).
I really wish you could only advance in Open play, or that Open money/ships/reputation were separate from Solo money/ships/reputation.
Yes, I know some don't want to have to deal with other players, great, there is a solo mode.
But the fact that solo and open are tied together means you can play in complete safety, get your uber ship, then jump into open.
Really feels like the game is losing some of its potential by having a 100% safe mode.
Unfortunately the internet always breeds a high percentage of players who's only fun is to grief or spoil other people's gameplay! They then hide behind the old claim "This is part of the game and there should be risk, if you don't like it you should not be playing". The potential problem, and I hope FD will address it, is the lack of serious gameplay consequences for these griefers. It is legitimate gameplay to be a pirate/murderer/criminal, but, as in real life the criminal should accept the consequences which is they are increasingly marginalised and segregated from the law abiding community and find it ever harder to access aspects of gameplay in the higher security/High Tech areas of ED.
I guess it will be a balancing issue, but if you get the consequences for criminal behaviour right, then open play becomes realistic. In the meantime a lot of people will want to play Solo.
PS I played EVE for 3 years and still do.
