Picking up on Riceman's thread, but narrowing it significantly, if you could give 38 Studios just one (yes one!) piece of very specific advice, what would it be? So you're called into a meeting at the company and told that your suggestion
will be implemented, but it has to be specific. What's your response?
And it can't be "make it fun" or "stomp out RMT" or stuff like that. They've undoubtedly been through all those issues many times over by now. Instead, it has to be specific and concrete, maybe even things that might not have occurred to them. One example could be "don't make the names of locations impossible to pronounce." Why do that? To help avoid turning off casual/new gamers from getting interested in the game, as they'd probably look at a name like Althezamn-Iridyl and conclude that this game is strictly for uber-fantasy fans. (This of course assumes that the plan is to attract as many new gamers as possible.) On the other hand, don't go with lame, disney-esque names either, like Stormwind.
BTW, anyone who sneaks in two or more suggestions gets negative infinity points.
