It's an excellent expansion but there are some choices in design that I wouldn't have done. Way too much reliance on quick time events and scripted deaths to give a sense of danger (which is jarring since V can very well turn right around and be a war god once the scripted stuff ends). Having said that: loved the writing, the acting is top notch, the new area and variation on gigs are really fun. If you have Cyberpunk already, this should be a no-brainer. If you don't, I'd still highly recommend it. Would give 4.5 stars if I could.
Just noticed that all the leading reviews are from launch. If you're debating this game, don't be put off by any complaints you see from before Phantom Liberty launched. CD really polished this up since then and I wouldn't hesitate to recommend it - it's easily one of the best rpgs of all time now, it just had a rocky start at life.
