BG3 is a very different bet. We know CRPGs are popular, we know Larian games get good reviews, we know the Baldur’s Gate 1 and 2 games established the series and are well regarded. All of this makes it a somewhat limited risk, and to top it all off, it is Larian taking the risk, not WotC, and they are experienced in making these kinds of games.
On the other side we have WotC hiring a huge team to churn out a 3D VTT when those have far less of a track record than CRPGs and WotC has much less of a track record with them than Larian with games. Yet the investment by WotC is probably bigger than Larian’s, despite their poor to nonexistent track record.
On the upside WotC is bigger than Larian, so WotC can survive what would kill Larian, but as an investment, Larian is the safer bet.
WotC stepping into VTTs was inevitable, they did not dip their toe in the water however, but jumped in head first. It certainly can work out, but it is more high risk / high reward than gradually building up to it
