Sins of A Solar Empire Trinity Edition includes:
Not checked if price is available in store as I ordered online.
6% cash back available from Quidco and Top Cashback (78p).
The installation is on a single DVD, housed in a DVD case in a cardboard slip sleeve.
Included in the pack is a large (between A3 and A2 sized) double sided colour poster of the three species tech trees. And a black and white paged manual.
If you require the latest patch you have to tie serial number to Impulse (a bit like Steam client). Unlike Steam I have been able to get two retail game serial numbers removed from my account, so able to sell game on again. You don't need Impulse client running in order to load game, but you do need it running to get patched.
Sins single player game isn't a story driven level progression experience, like Home World series for example. But single skirmish levels based on various options with some epic fleet scale battles.
A demo is available from Impulse (see link in next post).
