Avatar Hangout uses the same viewer and application as Second Life but is attempting to provide a cheaper alternative. A lot of the big sims in SL are already looking to move across as SL prices increase. Full Sim with full perm 65536 Sqm with 15000 prims is only $75 USD/Month Full Sim with Low prims and full perm 65536 Sqm with 5000 prims is only $45 USD/Month Â½ Sim 32768 Sqm with 7500 prims is only $38 USD/Month Â¼ Sim 16384 Sqm with 3750 prims is only $20 USD/Month Just an example of the cheap available land on Avatar Hangout. Other advantages include free uploads of textures and sounds for a limited time and the ability to freely create mega prims. At the moment it looks a bit rough but I can predict a price war as these new open source sims start multiplying.
