Because a single-player game making the switch OVER to multi-player Only and struggling would put off other developers doing something similar in the future...so helping to secure future development of single-player games
because it makes it more likely that any Future Elite games will be developed to include a single-player experience rather than multi-player only
Etc etc...
A single feature does not make a switchover,
much like a single swallow doesn't bring summer.
Reinforcing the exaggeration policy driven in this forum with your doomsaying
is a result.
