They do ... to a degree ... but you seem to be confusing T11 - which is essentially just a free-to-play Facebook app, after all - with something far more grandiose; a full-scale, full-price management simulation like SI's FM, for instance.
I tend to look at T11 as a casual, slightly more advanced version of what used to be know back in the day as 'PBM'. Though I suspect very few (if any) members here have heard of that!
