The choice is purely aesthetic. Both sides have equal mechanics, the game balances the different factions power levels.
Choose whichever faction appeals to you visually, neither side has any superior advantage over the other in terms of game play. Winning is about correct troop selection and deployment within the restrictions of your given scenario, not which faction you are using.
Your answer is going to be different from person to person..... Orks are better at combat, Tau are better at shooting. Depending on what you are looking for, both armies are amazing.
Man is a lot better than Wolves. The more I know about people, the better I like dogs -Wolves included.
Better in or at or with what?Well, pandas are cuter, but wolves are a vital part of the ecosystem.
No they are the same size unless you take into account the extra modifications the 40k Orks have.
no wolves have NEVER beat at st Andrews blues in the prem
Try it out
Technically you can play any army against any army, and any army with any army, except where rules specifically state that you may not (E.g. Black Templars may never ally with an army containing pyschers) It would however be extremely unusual, but so long as you have a good background story, it should be fine.
No, for once wolves are real and zombies no. Most people are not so scared of zombies and are way too scared of wolves.
No. Better than Wolves does not use the Forge API anymore, which renders it incompatible with most other major mods. Anyway, industrialcraft does not fit in very well with Better than Wolves. If you were to play the two mods alongside each other, you'd find that it would make the gameplay completely unbalanced.
No, they don't climb any better than dogs.
This depends on the size of the squad, and in what scenario they are. If it is 1 Space Marine vs. 10 Fire Warriors, the Marine doesn't stand a chance and vice versa. Also, Space Marines are better all-rounders where as Fire Warriors are excellent long range firepower troops. At range the Fire Warriors should come out tops, but at short range and close combat the Space Marines would crush the Fire Warriors. On a point by point basis, the average Marine is worth 16 points, and a Fire Warrior is a worth 10. So if the squads are equal in number, the Space Marines are technically a stronger squad.
Yes because they are bigger and better. There is no real 'better' to speak of without listing something they are better in. A wolf may be better at howling, but a fox may be better at digging. Generally speaking, neither is better than the other.
