It is a pity that TML simulators do not meet more audience. It may be assumed that some technical faults discourage some players but it must be admitted that Fernbus and TBS have many many qualities. Thus, the bus and coach market is a very small market.
"The bus" will be decisive because it deals with urban transport, which seems to interest more people. But let us not forget that OMSi owns its success especially to the existence of more than a hundred of maps, developed with passion and patience.
Developing a map remains something very complex. For example, BS18, which has existed for a long time, still doesn't have a real alternative map, whereas modding tools are present from the beginning.
For my part, I think that an idea to develop the audience of TML would be to use the base "The bus" to make it a sort of" global simulator". Buses and coaches would remain the heart of the business, but why not make it cohabit one or the other truck (urban delivery, garbage trucks for example)? or just cars? or road maintenance vehicles (those washing of former "TML kehrmaschinen simulator"). That could be a nice multiplayer experience, also with a goal which will bring XP points to rate all players (going from A To B is already a task).
I have to admit that such a game is perhaps already the goal of LOTUS. But looking at the development of TML games, it's perhaps not so far as we expect it...
So friends, what do you think players expect from a simulator today? What could be the "hook" to success ?
