Shieldwall is Demon???s Rise 3 in all but name - and as far as I???m concerned, that???s awesome!
If you liked DR, this is more of the same - different characters, some spell/ability reuse, some monster reuse. Not a ton of reused assets - game and encounters feel fresh - but the lineage feels very familiar.
DR, DR2, and STA have given me many hours of enjoyment and halfway through shieldwall, I???m enjoying it just as much. I find the replay value on these games to be quite high Dash I???ve run through them to her three times with different groups, which is a lot of the fun.
