Quite frustrating really - I feel the quality and breadth of mods that were available for SH3 really outstrip what is there for SH4.
Found myself going back to old SH3 this week... I mean SH4 looks the bizz.. but its just lacking in the mods and available tools department. I know that SH3 has been around for a lot longer, but still, SH4 seems to have missed the boat a bit in terms of mod development.
And SH5 ... ugh
Won't even go there.
