Contrariwise, there is a large majority who would like various problems and deficiencies corrected before the limited resources of VSTEP are diverted to cater to the demands of a small, but vocal, minority.
Should the Titanic be given priority over the needs of that majority, they are likely to become very angry.
The argument that including Titanic in SSE would increase sales is not a rational one. That ship is available in the less expensive SS2008 that runs better, for that limited purpose, than SSE does.
It is unlikely that anyone would buy SSE just to get Titanic. Most of those who want Titanic already own SSE, so the potential for additional sales is small.
