I get your points. I don't necessarily disagree either. I know someone who is prepared to drop thousands for one of the Mansions that is due to be released soon. It's like Shroud of the Avatar in that respect, without the nostalgia driving the willingness to spend incredible amounts of cash. You are definitely correct that people will spend a ton of money in this game. I'm just not so sure it's necessarily a bad thing. Boats are a good example. Like you I think they will be pretty pricey. But I know that someone in the guild I plan to run with will buy one, so I don't care. Worse case scenario you buy passage on someone's boat. Kinda cool I think.
I guess my point is, we don't have enough concrete information to make a judgement either way on whether or not real world money is going to negatively affect Revival. If the game is PvP territory centric, then obviously the guilds with the largest whales will have a huge advantage due to resources they have bought (boats for trading, farms, personal crafting stations in homes, etc). If the game is more 'contend with The Old Gods' PvE driven, maybe not so much. Remains to be seen. I suspect the "Have's" versus "Have nots" will be a big factor as well. If you are strutting around being a dick with your cash shop opulence, that's painting a huge target on your back. From what I've read, if 200 players decide to burn your $3k Mansion to the ground, it's doable. And no you won't lose the real estate, but supposedly the cost to rebuild will be considerable. And if you can't pay real world money to do so, that's significant.
The game is really a bunch of ideas more than anything right now. The themes and design that have been talked about are so compelling I kind of just want to see it in action. Whales or not.
