I just got the download for MP 41 and after toying around with it for an hour I have to say thats its the best entity pack so far imo.
It includes all the stuff you need for a TR style game and theres PLENTY of it. The vids show not even half of whats included. There are enough different doors and windows to build 5 different dungeons without repeating anything and the switches, staues, fire pots, columns etc. allow to create games that look like nothing we've seen yet. The large wall/ceiling fans and the tubes are suitable for all steampunk settings and make for great light effects
Especially the hints and non-working switches are really adding to the atmosphere and they all include colorfull huds. There are even the cogs you had to find and insert in the very first TR to make some things work and they come with a dozen animated/non-animated varieties so you can build really large machines
The pain boxes are a terrific invention, they will also work great with force fields etc. whats more they allow you to actually make every small spot of fire a *pain*
Personally I found that the segments from the "Dark Egypt" MP dont match too well with MP 41, but Bucketheads "Ancient" pack and CheeseCakes "Tomb Pack" are perfect (both avilable p.e. on
