Can pretty much guarantee they wouldn't have had the conflict they are having now, without the underground resources in the Donbass.Crimea's the main tourist attraction though, and that has never really been Ukraine.
Natural resources are definitely a plus, but think about the fate of most resource rich countries (we're an exception, and even then not an entirely good one) when the USA, Europe and NATO (the "good" guys?) start taking an interest. It's not a good situation to be in, you'd almost rather have nothing but soil.
