Not to mention the huge library of games from B to AAA that use unreal/unity with things like cool gameplay, multiplayer and multi platform (PC and consoles).. this comment made no sense.
The comment hits closer to the bullseye than you realize. When you buy into an engine like UE and especially Unity you look at the successes on consoles but in reality you're in for a world of hurt if you want to achieve the same level of perf on the older consoles. It's like the difference between a stock WRX and a rally team prepped WRX - same car sure but the perf is vastly different and if you want to compete on that level you have a lot more work ahead of you.
